Abstract:
Abstract Calcium homeostasis in the extracellular fluid is tightly controlled and defended physiologically. Hypercalcemia always represents considerable underlying pathology and occurs when the hormonal control of calcium homeostasis is overwhelmed. The major hormones that are responsible for normal calcium homeostasis are parathyroid hormone and 1,25-dihydroxyvitamin D; these hormones control extracellular fluid calcium on a chronic basis. Over- or underproduction of these hormones or the tumor peptide, parathyroid hormone-related peptide, are the major causes of aberrant extracellular fluid calcium concentrations. These hormonal defense mechanisms are reviewed here.

Abstract:
Acute and chronic exposure to high altitude induces various physiological changes, including activation or inhibition of various hormonal systems. In response to activation processes, a desensitization of several pathways has been described, especially in the adrenergic system. In the present study, we aimed to assess whether the hypophyseal hormones are also subjected to a hypoxia-induced decrease in their response to hypothalamic factors. Basal levels of hormones and the responses of TSH, thyroid hormones, prolactin, sex hormones, and growth hormone to the injection of TRH, gonadotropin-releasing hormone, and growth hormone-releasing hormone (GHRH) were studied in eight men in normoxia and on prolonged exposure (3–4 days) to an altitude of 4,350 m. Thyroid hormones were elevated at altitude (+16 to +21%), while TSH levels were unchanged, and follicle-stimulating hormone and prolactin decreased, while leutinizing hormone was unchanged. Norepinephrine and cortisol levels were elevated, while no change was observed in levels of epinephrine, dopamine, growth hormone (GH), IGF-1, and IGFBP-3. The mean response to hypothalamic factors was similar in both altitudes for all studied hormones, although total T4 was lower in hypoxia during 45 to 60 min after injection. The effect of hypoxia on the hypophyseal response to hypothalamic factors was similar among subjects, except for the GH response to GHRH administration. We conclude that prolonged exposure to high-altitude hypoxia induces contrasted changes in hormonal levels, but the hypophyseal response to hypothalamic factors does not appear to be blunted.

Abstract:
Non-alcoholic fatty liver disease (NAFLD) is a common manifestation of metabolic syndrome. In addition to lifestyle, endocrine hormones play a role in the dysregulation of hepatic metabolism. The most common endocrine hormones contributing to metabolic syndrome are alterations in the levels of thyroid hormones (THs, predominantly in subclinical hypothyroidism) and of sex hormones (in menopause). These hormonal changes influence hepatic lipid and glucose metabolism and may increase hepatic fat accumulation. This review compares the effects of sex hormones, THs and the respective stimulating hormones, thyroid-stimulating hormone (TSH) and follicle-stimulating hormone (FSH), on the development of hepatosteatosis. TSH and FSH may be more relevant to the dysregulation of hepatic metabolism than the peripheral hormones because metabolic changes were identified when only levels of the stimulating hormones were abnormal and the peripheral hormones were still in the reference range. Increased TSH and FSH levels appear to have additive effects on the development of NAFLD and to act independently from each other.

Abstract:
Hormones serves as natural chemical triggers that regulate various processes within the human body, including growth, emotional states, and cognitive processing. Extensive research has been conducted to explore the correlation between hormonal effects and cognitive function; these studies have examined a variety of factors such as aging, pregnancy, post-natal states, emotions, and stress. This article focuses on the impact of hormonal changes on neuronal networks and the mechanisms underlying cognitive function. Hormones possess the ability to influence multiple processes in the human body, including emotions and cognition. The effects of hormones on cognitive function vary depending on the specific hormone involved. Furthermore, hormone levels that are too low or too high can lead to both positive and negative outcomes. Therefore, understanding the influence of sex hormones on cognition is a valuable endeavor.

Abstract:
A deep understanding of the role of specific hormones in genital development is key to designing effective therapeutic approaches. Factors such as testosterone deficiency, growth hormone disorders, or other hormonal imbalances can be targets for hormonal interventions that can affect penis size. This study aimed to explore the role of hormonal aspects in micropenis disorders. The literature search process was carried out on various databases (PubMed, Web of Sciences, EMBASE, Cochrane Libraries, and Google Scholar) regarding the role of hormonal aspects in micropenis disorders. This study follows the preferred reporting items for systematic reviews and meta-analysis (PRISMA) recommendations. Aspects of the hormonal role in micropenis include several key elements that influence the development of genital organs in men. Hormones, such as testosterone, growth hormone, estrogen, and dihydrotestosterone (DHT), play an important role in stimulating penis growth and development. Proper hormonal balance is necessary for normal genital development, and disturbances in the production of or response to these hormones may contribute to conditions such as micropenis.

Abstract:
Lipid-soluble vitamins (vitamins A, D, E, and K) are actually hormones (exohormones), as they can be directly bound by hormone receptors or are in connection with molecules, which influence hormone receptors. Vitamin D is a transition between endo- and exohormones and the possibility of similar situation in case of other lipid-soluble hormones is discussed. The perinatal exposition with these “vitamins” can cause faulty perinatal hormonal imprinting with similar consequences as the faulty imprinting by the synthetic endohormones, members of the same hormone family or industrial, communal, or medical endocrine disruptors. The faulty imprinting leads to late (lifelong) consequences with altered hormone binding by receptors, altered sexuality, brain function, immunity, bone development, and fractures, etc. In addition, as hormonal imprinting is an epigenetic process, the effect of a single exposure by fat-soluble vitamins is inherited to the progeny generations. As vitamins are handled differently from hormones; however, perinatal treatments take place frequently and sometimes it is forced, the negative late effect of faulty perinatal vitamin-caused hormonal imprinting must be considered.

Abstract:
summary: This article considers the establishment of the category of "hormone-dependent cancers," identified around the middle of the twentieth century as cancers sustained by particular hormones. A comparison of hormonal treatments for prostate cancer and those for breast cancer reveals that the genesis of "hormone-dependent cancer" as a biomedical category relied upon assumptions that cast androgens and estrogens as opposing ends of a gendered hormonal binary of health and disease. In the 1930s, cancer researchers claimed "female sex hormones" (estrogens) exacerbated breast cancer and "male sex hormones" (androgens) prevented it. In the early 1940s, Dr. Charles Huggins applied the opposite logic to the treatment of human prostate cancer, which he determined to be "hormone-dependent." As "hormone dependency" was also recognized in human breast cancer over the subsequent decades, estrogen claimed a prominent place in discussions of breast cancer's causation, diagnosis, and treatment. This close association between estrogen and breast cancer contributed to reinterpretations of both biomedical categories.

Abstract:
Recent years have seen growing scholarly interest in female physiology in general. Moreover, particular attention has been devoted to how concentrations of female sex hormones vary during the menstrual cycle and menopausal transition and how hormonal contraception and hormonal therapy influence skeletal muscle tissue. While much effort has been paid to macro outcomes, such as muscle function or mass, rather less attention has been paid to mechanistic work that may help explain the underlying mechanism through which sex hormones regulate skeletal muscle tissue. Evidence from animal studies shows a strong relationship between the female sex hormone estrogen and satellite cells (SCs), a population of muscle stem cells involved in skeletal muscle regulation. A few human studies investigating this relationship have been published only recently. Thus, the purpose of this study was to bring an updated review on female sex hormones and their role in SC regulation. First, we describe how SCs regulate skeletal muscle maintenance and repair and introduce sex hormone signaling within the muscle. Second, we present evidence from animal studies elucidating how estrogen deficiency and supplementation influence SCs. Third, we present results from investigations from human trials including women whose concentrations of female hormones differ due to menopause, hormone therapy, hormonal contraceptives, and the menstrual cycle. Finally, we discuss research and methodological recommendations for future studies aiming at elucidating the link between female sex hormones and SCs with respect to aging and training.

Abstract:
Marine mussels accumulate amino acids and glucose from seawater against considerable concentration gradients. The principal site for this uptake is the gill. Previous studies using intact, isolated gills from marine mussels have suggested that the transport mechanism involves coupling to Na⁺, similar to the mechanism of secondary active transport of amino acids and glucose in vertebrate epithelia, but until this dissertation there had been no rigorous test of this hypothesis. Brush border membrane vesicles (BBMV) were prepared from the gills of the marine mussel, Mytilus edulis, by differential and sucrose density centrifugation. The preparation procedure isolated a population of membranes enriched in brush border membrane markers. The transport of amino acids by two pathways, the alanine-lysine pathway (AK) and the alanine-proline pathway (AP), and the uptake of glucose was studied in the BBMV. The mechanism of transport through the three transport pathways is BBMV involved coupling to Na⁺. Concentrative uptake through the AK pathway, which transported alanine and lysine, also occurred in the presence of Li⁺ and K⁺ gradients. This pathway was the major route for alanine transport in BBMV. The AP pathway transported alanine and proline, and was strictly dependent on Na⁺. Glucose transport in gill BBMV resembled quite closely the Na⁺-coupled transport of glucose in vertebrate epithelia in such characteristics as Na⁺ and substrate specifically, and electrogenicity. Transport through the two amino acid uptake pathways (AK and AP) and through the glucose uptake pathway could be described by Michaelis-Menten kinetics, with high substrate affinities (K(t)'s below 10 μM). Furthermore, it is likely that multiple Na⁺ ions are involved in the transport of these amino acids and glucose in mussel gill BBMV. It appears that these transporters are adapted for function at low substrate concentrations and against large concentration gradients.

Resumo: O tecido prostático é susceptível aos desníveis hormonais provocados, principalmente pelo processo de envelhecimento. A hiperplasia benigna prostática e o câncer de próstata são doenças que acometem uma grande parcela da população masculina, e parecem estar envolvidas com alterações hormonais. Por isso, o esclarecimento dos processos celulares e teciduais envolvendo os hormônios sexuais: testosterona e estradiol são, sem dúvida, importantes para o entendimento da etiologia desses processos patológicos. O gerbilo (Meriones unguiculatus) foi utilizado como modelo experimental pois, segundo a literatura, é susceptível ao aparecimento de lesões autóctones e responde bem à carcinogênese experimental, mostrando-se um bom modelo experimental. Numa primeira etapa, foram utilizados animais de três idades diferentes: púbere, adulta e senil. Esses animais foram submetidos à suplementação androgênica e as próstatas ventrais foram destinadas a análises histopatológicas, quantitativas, imunocitoquímicas e ultraestruturais. Foi observado aumento no peso da glândula e também na altura das células epiteliais em todas as idades. Tal aumento reflete o aumento da capacidade sintética observada pela dilatação das organelas de síntese, às vezes de aspecto vesiculoso, ocupando toda a região supranuclear. Nos animais adultos e velhos foram notadas regiões hiperplásicas e displásicas freqüentemente associadas a Neoplasias Intraepiteliais de diferentes graus e a adenocarcinomas. Houve aumento na espessura da camada de células musculares lisas (CML) ao redor dos ácinos nos animais púberes e adultos, enquanto nos animais velhos houve diminuição dessa camada. Além disso, as CML se mostraram aparentemente hipertróficas e com maior atividade sintética nos animais púberes e adultos. Foi notado aparente aumento da vascularização periacinar, onde se observou a presença de freqüentes vasos sanguíneos em todas as idades após o tratamento. Ademais, em todas as idades foi observado aumento da densidade de marcação de receptores androgênicos após o tratamento, evidenciando a possível relação desses receptores com os efeitos observados. Em uma segunda etapa experimental, avaliou-se o efeito do estradiol sobre o tecido prostático intacto e hipoandrogênico em animais adultos, tentando com isso simular situações de descompensação hormonal, típicas da senilidade. As alterações epiteliais foram freqüentes nos animais tratados com estradiol onde se observou aumento na altura das células epiteliais, aparecimento de regiões de intensa displasia e hiperplasia, e a formação de PINs. Outro aspecto que independe da presença da testosterona é o arranjo dos elementos fibrilares e não fibrilares da matriz extracelular entre as CML, apontando para um possível papel dessas células no rearranjo e na síntese desses componentes após os tratamentos estrogênicos. Nos animais castrados observou-se acúmulo de elementos da matriz extracelular sob o epitélio e em animais intactos presença desses elementos dispersos e escassos. Em ambos os grupos: intactos e castrados, notou-se que as CML e os fibroblastos apresentam fenótipo secretor acentuado após o tratamento com estradiol. Houve aumento na densidade de marcação ERa e AR positivos em regiões de hiperplasia apontando para um possível papel desses receptores na formação de lesões pré-malígnas e malignas. Portando, conclui-se que o gerbilo é susceptível a ação da testosterona e do estradiol, os quais provocam desarranjos estruturais e ultraestruturais de cunho patológico e funcional, mostrando-se um ótimo modelo para o estudo das doenças prostáticas de etiologia hormonal

Abstract:
L'épithélium intestinal est caractérisé par un renouvellement et une différenciation continus dépendant des cellules souches somatiques situées au fond des cryptes. Le renouvellement rapide est assuré par plusieurs réseaux de voies signalisation dont la dérégulation peut être à l'origine de l'initiation et/ou de la progression tumorale. Mon laboratoire d'accueil a décrit l'implication des hormones thyroïdiennes et de leur récepteur nucléaire TRa1 dans le contrôle de l'homéostasie de l'épithélium intestinal via la régulation de la voie Wnt/b-caténine d'une part et l'implication de TRa1 dans l'induction de tumeurs intestinales grâce à des souris surexprimant TRa1 d'autre part. De plus, dans un contexte APC muté, l'expression transgénique de TRa1 accélère la progression tumorale et favorise la dissémination métastatique. Des analyses transcriptomiques mettent en évidence une forte activation de la voie Wnt par TRa1. Ces résultats ont été confirmés chez l'homme en étudiant la régulation de la voie Wnt par TRa1 dans des carcinomes colorectaux (CRC). Nous avons confirmé la surexpression de TRa1 dans les tumeurs humaines et validé son impact sur la voie Wnt tant dans les tumeurs humaines que dans des lignées cellulaires et sur leur agressivité. L'ensemble des données montre une forte implication de TRa1 dans la tumorigenèse chez la souris et chez l'homme et ouvrent des portes pour des recherches visant TRa1 comme cible de traitement thérapeutique contre le cancer
The intestinal epithelium is characterized by constant renewal and differentiation due to the presence of stem cells located at the bottom of the crypts. This permanent renewal depends on the crosstalk between several signaling pathways whose alteration can lead to tumor initiation and progression. Our team demonstrated the implication of the thyroid hormones and their nuclear receptor TRa1 in the control of the intestinal epithelium homeostasis through the regulation of the Wnt pathway. Moreover, the overexpression of TRa1 in the intestinal epithelium of mice is sufficient to promote tumor initiation, and in an APC loss of function context, it accelerates tumor progression highlighting its oncogenic potential. Through gene expression profiling, we highlighted an activation of the Wnt pathway activity by TRa1 during tumor progression. We next confirm these results in human patient samples by demonstrating that high TRa1 expression in tumors invariably is associated with an increased Wnt pathway activity. In addition, in CRC cell lines, TRa1-associated WNT pathway activation enhances their aggressiveness. Altogether these results showed the implication of TRa1 in intestinal carcinogenesis and open avenues for new therapeutic treatment against TRa1 targeting TRa1

Full text
Abstract:
Background: In recent years, compounded bioidentical hormone therapy (CBHT) has emerged as a popular alternative to manufactured, FDA approved hormone therapy (HT)-despite concerns within the medical community and the availability of new FDA approved "bioidentical" products. This study aims to characterize the motivations for using CBHT in a U.S. sample of ordinary midlife women. Methods: We analyze data collected from 21 current and former users of CBHT who participated in a larger qualitative study of menopausal decision-making among U.S. women. Interviews and focus groups were audio-recorded, transcribed verbatim, and analyzed thematically using an iterative inductive and deductive process. Results: Although women's individual motivations varied, two overarching themes emerged: "push motivations" that drove women away from conventional HT and from alternative therapies, and "pull motivations" that attracted women to CBHT. Push motivations focused on (1) fear and uncertainty about the safety of conventional HT, (2) an aversion to conjugated estrogens in particular, and (3) and overarching distrust of a medical system perceived as dismissive of their concerns and overly reliant on pharmaceuticals. Participants also voiced dissatisfaction with the effectiveness of herbal and soy supplements. Participants were attracted to CBHT because they perceive it to be (1) effective in managing menopausal symptoms, (2) safer than conventional HT, (3) tailored to their individual bodies and needs, and (4) accompanied by enhanced clinical care and attention. Conclusions: This study finds that women draw upon a range of "push" and "pull" motivations in their decision to use CBHT. Importantly, we find that women are not only seeking alternatives to conventional pharmaceuticals, but alternatives to conventional care where their menopausal experience is solicited, their treatment goals are heard, and they are engaged as agents in managing their own menopause. The significance of this finding goes beyond understanding why women choose CBHT. Women making menopause treatment decisions of all kinds would benefit from greater shared decision-making in the clinical context in which they are explicitly invited to share their experiences, priorities, and preferences. This would also provide an opportunity for clinicians to discuss the pros and cons of conventional HT, CBHT, and other approaches to managing menopause.

Abstract:
In this study, carbon cryogel was used as solid-phase extraction sorbent for the extraction of estrogenic hormones (estrone, 17β-estradiol, and 17α-ethinylestradiol) from water solution. The solid-phase extraction (SPE) method was optimized by choosing an appropriate mass of the sorbent, volume, and initial pH of estrogenic hormone water solution, as well as by choosing an appropriate organic solvent. The concentration of tested hormones after extraction was measured by liquid chromatography coupled with tandem mass spectrometry. Based on the obtained hormone recoveries, the following optimal conditions of the SPE procedure were chosen: 100 cm3 of hormone water solution at initial pH adjusted to 7, 20 mg of the sorbent, the methanol-dichloromethane mixture was used for hormone elution. Recoveries obtained under the optimal conditions ranged from 77 % for estrone, to 86 % for 17β-estradiol, with relative standard deviation from 7,4 to 18 %.

Abstract:
The effect of hormone treatment on the material properties of ligaments has been extensively studied for the anterior cruciate ligament (ACL). However, there have been few studies on the effects of hormones on the material properties of the shoulder. Shoulder ligaments contribute to overall shoulder stability, and a change in ligament properties could contribute to a change in overall shoulder laxity. Cynomolgus monkeys have served as nonhuman primate models in studies examining the effects of hormone replacement therapy on the cardiovascular system, as well as serving as a model for menopause, reproductive support structures, the knee joint and shoulder joint. The cynomolgus macaques are commonly used for studies involving hormone replacement therapy because they have 28-day menstrual cycles with very similar hormonal patterns to that of women. This study uses female cynomologus macaque (Macaca fascicularis) monkeys as an animal model of the human shoulder to determine if estrogen has an effect on the strain distribution of the inferior glenohumeral ligament (IGHL).

Abstract:
Peripheral giant cell granuloma (PGCG) is a relatively Common reactive exophytic lesion of the oral cavity. The influence of hormones has been suggested as contributory factor in PGCG development and predominance of these lesions in young females as well as some previously reported pregnancy related cases support this belief. It has been observed that majority of lesions present in the 4th decade of life, when hormonal changes are more pronounced. Cailluette and Mattar in their study found that peripheral giant cell granuloma are under the influence of the ovarian hormones. However Chambers and Spector suggested peripheral giant cell granuloma to be enhanced by pregnancy rather than being pregnancy dependent. The responsiveness of gingiva to these hormones along with the immunosuppressive actions of the hormones contributes to the growth of the lesion. Clinically, PGCGs may present as polypoid or nodular lesions, predominantly bluish red with a smooth shiny or mamillated surface.This poster will review the literature available on the association of Massive Peripheral Giant Cell Granuloma With Pregnancy with focus on possible causes of PGCG during pregnancy.

Abstract:
The aim of this paper is to describe complex homeoretic and homeostatic mechanisms in dairy cows during the peripartum period. The endocrine system has a key function in regulating the adaptation of metabolism during the peripartum period. Homeoresis represents the functioning of the endocrine system and metabolism in conditions when the organism must primarily provide certain physiological processes, such as fetal growth or lactation. Then the function of all tissues is adjusted to the new situation. Homeoretic hormones (growth hormone, prolactin, glucocorticosteroids, thyroid hormones, insulin, glucagon and leptin) in dairy cows in the peripartum period play a key role in maintaining high lactation and maintaining cow health.

International Scientific Congress of Pure, Applied and Technological Sciences. Rimar Academy, 2022. http://dx.doi.org/10.47832/minarcongress5-22.

Full text
Abstract:
Hypothyroidism is a medical state referring to the lack of secretion of thyroid hormones (THs) in the body. It occurs when the thyroid gland starts to produce and secrete a small amount of thyroid hormones Thyroxine (T4) and Triiodothyronin (T3), this will affect body cells, resulting in a slowing of the body's metabolic rate, weight gain, and tachycardia. Visfatin and adiponectin are two hormones from type adipokine produced from fat tissue. Those hormones have an important function in protein, lipid and glucose metabolism, as well their role in energy expenditure. Eighty cases of both sexes (male and female) have been collected from the hospitals and private laboratories of Iraq. They are divided into two groups. Group1 (control group) includes (40) healthy individuals and the group2 includes (40) hypothyroid patients, All patients and controls underwent history taking, determination of levels of visfatin, adiponectin, Thyroid-stimulating hormone (TSH), T4, T3 and lipid profile. The results showed that Visfatin levels in group 2 were significantly higher than in group1, on the other hand, Adiponectin levels decreased in group2 compared with the control group at probability (P≤ 0.01), and concerning the lipid profile, there was a significant increase in the levels of lipid parameters total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL-c) and very low density lipoprotein (VLDL) while high density lipoprotein (HDL) was decreased in group2 compared to control group

Abstract:
Hormones such as estrogen are known to have an effect on the biomechanical properties of certain ligaments such as the anterior cruciate ligament in the knee; however, relatively little is known about its effect on the ligaments of the shoulder. The inferior glenohumeral ligament (IGHL) is a static stabilizer of the shoulder that prevents anterior translation of the humeral head. Alterations to the properties of this ligament can result in capsular stretching, increased laxity, and ultimately instability. The cynomolgus macaque (Macaca fascicularis) shares many hormonal similarities with humans including a 28-day menstrual cycle and is a commonly used model for hormone replacement therapy studies. This study uses the female cynomolgus monkey as a model of the human shoulder to determine if estrogen has an effect on the regional surface strain behavior of the inferior glenohumeral ligament.

Abstract:
The article discusses novel data on impact of altered deuterium body content on endocrine function. The paper represents the results of investigation of thyroid hormones and pituitary thyroid stimulating hormone production during gradual increase of deuterium body content. The research revealed sensitivity of the endocrine glands to changes in deuterium content. The revealed findings are considered from the point of view of the regulatory and dysregula-tory aspects of action of the hydrogen isotope on hormone genesis.

Abstract:
Neuroscience is an “umbrella” concept which incorporates more scientific domains that permit the accomplishment of transdisciplinary study at the crossroads of biochemistry, physiology, and psychology. The theoretical study concentrates on the analysis of several scientific point of views and research of the main 3 hormones/ neurotransmitters, which define the characteristics of human personality situated in the brain and the spinal cord, serotonin, dopamine, and norepinephrine. The above-mentioned hormones/neurotransmitters have beenm studied through the prism of biochemistry and physiology, however, much less through that of psychology. More studies have proven the direct connection between the variation of an individual’s personality and the levels of neurotransmitters present in the system. The previously stated facts highlight the necessity of deepening this study, especially in the domain of correlation between the abundance/absence of a certain hormone/neurotransmitter in the human body and the traits of personality.
