Maddox Dairy, located in Riverdale, CA, USA, is a Holstein herd that milks 3500 cows with a 305-day mature-equivalent milk production of 12 800 kg, and they have been producing high genetic animals by embryo transfer (ET) since the early 1980s. Invivo-derived embryos from Holstein donors were transferred fresh (grade 1 or 2) or frozen (grade 1), at morula (4), early blastocyst (5), or blastocyst (6) stage, to virgin heifers (VH, natural oestrus, 13-15 months old) or lactating cows (LC, Presynch-Ovsynch, 86 days in milk, first or second lactation) 6 to 9 days after oestrus. Pregnancy diagnosis was done by transrectal ultrasonography at 32-46 days in VH and by the IDEXX PAG test at 30 days in LC. June, July, August, September, and October were called critical months (first service AI conception rate drops below 44%) and compared with the other months. The data from 32 503 ETs between January 2008 and December 2018 are summarised on Table 1. Pregnancy rates (PR) are lower for LC recipients than for VH. Embryo transfers performed 7 or 8 days after oestrus had higher PR in both types of recipients and embryos, but Day 6 and 9 oestrus are also used with fair results. The season does not seem to affect PR. There is not enough difference in the combination of stage and days from oestrus for invivo-derived embryos. These numbers do not belong to a planned experiment. Several management changes during the years were made, which make it very difficult to apply statistical methods to analyse the data correctly. They are used as a tool to make decisions in an attempt to improve future results.

Food-borne diseases are the global public health problems encountered as a result of consumption of contaminated foods. To this end, this study was designed to evaluate the microbial quality of fura-nunu sold in Eiyenkorin, Kwara State, Nigeria. Samples of fura-nunu were collected at different locations within Eiyenkorin and were transported to laboratory for analyses. Microbiological analyses were performed using standard methods. Data obtained from microbial counts were subjected to analysis of variance (ANOVA). Results of total heterotrophic bacteria count (THBC), total coliform count (TCC) and total fungal count (TFC) of fura-nunu indicated that THBC ranged from 1.6 ± 0.03 × 107 - 2.3 ± 0.01 × 107cfu/ml, TCC ranged from 2.5 ± 0.71 - 15.0 ± 1.41 cfu/100ml while TFC was between 4.0 ± 0.41 × 106 and 5.0 ± 5.58 ×107 cfu/g. There were significant differences (P<0.05) in THBC, TCC and TFC of fura-nunu samples. pH values ranged from 4.25 ± 0.31 – 5.30 ± 0.21. The identified bacteria with percentage occurrence (%) include; Lactobacillus spp. (14.81%), Staphylococcus aureus (12.96%), Escherichia coli (17.59%), Bacillus subtilis (6.48%), Pseudomonas aeruginosa (3.70%), Enterococcus spp. (8.33%), Micrococcus spp. (6.48%), Salmonella spp. (13.88%), Klebsiella spp. (4.62%) and Lactobacillus plantarium (11.11%). Fungi species and prevalence (%) were Aspergillus flavus (21.21%), Aspergillus niger (30.30%), Saccharomyces cerevisiae (16.66%), Penicillium spp. (12.12%) and Mucor spp. (19.69%). Results of handling and hygienic practices showed poor handling, storage and hygienic practices by fura-nunu vendors. Hence, there is need for proper education of the vendors on general food safety practices.

ObjectiveUniversal Basic Income (UBI)—a largely unconditional, regular payment to all adults to support basic needs—has been proposed as a policy to increase the size and security of household incomes and promote mental health. We aimed to quantify its long-term impact on mental health among young people in England.MethodsWe produced a discrete-time dynamic stochastic microsimulation that models a close-to-reality open cohort of synthetic individuals (2010–2030) based on data from Office for National Statistics and Understanding Society. Three UBI scheme scenarios were simulated: Scheme 1—Starter (per week): £41 per child; £63 per adult over 18 and under 65; £190 per adult aged 65+; Scheme 2—Intermediate (per week): £63 per child; £145 per adult under 65; £190 per adult aged 65+; Scheme 3—Minimum Income Standard level (per week): £95 per child; £230 per adult under 65; £230 per adult aged 65+. We reported cases of anxiety and depression prevented or postponed and cost savings. Estimates are rounded to the second significant digit.ResultsScheme 1 could prevent or postpone 200 000 (95% uncertainty interval: 180 000 to 210 000) cases of anxiety and depression from 2010 to 2030. This would increase to 420 000(400 000 to 440 000) for Scheme 2 and 550 000(520 000 to 570 000) for Scheme 3. Assuming that 50% of the cases are diagnosed and treated, Scheme 1 could save £330 million (£280 million to £390 million) to National Health Service (NHS) and personal social services (PSS), over the same period, with Scheme 2 (£710 million (£640 million to £790 million)) or Scheme 3 (£930 million (£850 million to £1000 million)) producing more considerable savings. Overall, total cost savings (including NHS, PSS and patients’ related costs) would range from £1.5 billion (£1.2 billion to £1.8 billion) for Scheme 1 to £4.2 billion (£3.7 billion to £4.6 billion) for Scheme 3.ConclusionOur modelling suggests that UBI could substantially benefit young people’s mental health, producing substantial health-related cost savings.

Background: Dialysis access is an essential part of hemodialysis. Determining the access blood flow (Qa) can help predict arterio-venous fistula thrombosis. Qa determination by the urea method, which was previously described in the past is simple and is available in most of the dialysis units but was not be able to predict arterio-venous fistula thrombosis. Aim: To compare the efficacy of Qa determination by the urea method and by ultrasound dilution methods in predicting arterio-venous fistula failure. Methods: Qa was measured by urea method and by ultrasound dilution simultaneously, every 3 months for a period of 1 year, in stable chronic hemodialysis patients with arterio-venous fistula. Arterio-venous fistula failure determined by clinical parameters and confirmed by Doppler ultrasound before sending the patient for interventional angioplasty. Results: This study enrolled a total of 16 patients, with 63% being male, 75% with lower-arm arterio-venous fistula and around 43% with previously done angioplasty. 59-Qa measurements were done, and 6 patients underwent angioplasty (one patient for severe upper limb edema, one for access thrombosis, and four for access dysfunction). Qa determination by the urea method had non-significantly lower Qa, (745 mL/min (interquartile range: 509–1143) and 779 mL/min (interquartile range: 530–1160), (p = 0.58)) and high correlation (r = 0.83, p < 0.001) to Qa by ultrasound dilution. The cut-off criteria with its sensitivity and specificity in predicting the access failure were 440 mL/min, 66.67%, and 96.15% for Qa determination by the urea and 400 mL/min, 66.67% and 90.38% for Qa by ultrasound dilution, respectively, with no difference in the area under the receiver operating characteristic curve. Conclusion: Measurement of Qa determination by the urea method is well correlated with Qa by ultrasound dilution and can be used to predict vascular access failure.

In this work, pseudo-stem of a banana plant was used as a sustainable and affordable source to prepare porous carbon materials (PCM) on a large scale. After fine treatment, the material was annealed at 500, 600, and 700 °C using a tube furnace under nitrogen flow. The prepared materials were characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). FT-IR spectra show that the broad peak at the range of 1110-1160 cm-1 comes from the superimposed peaks of C-N for a single or more than one functional group which debunks the possibility of generating nitrogen-doped carbon. TEM and SEM analyses confirmed the porous structure of PCM with the pores connected to one, and a spongy structure was observed in the prepared carbon material. XRD analysis revealed that the carbon materials are crystalline. XPS investigation provided information regarding the dimension of which elements are present in the valence states and constituent elements, depicting the presence of a dominant graphitic C1speak at approximately 284 eV, along with a distinct O1s peak at around 532 eV. Additionally, a relatively weaker N1s peak (approximately 400 eV) was observed. Dhaka Univ. J. Sci. 72(1): 63-70, 2024 (January)

The purpose of the work – study of morphophysiological profle and non-specifc protective forces of the body of service dogs in the conditions of a canine center against the background of prevention of immunodefciency with biological preparation Dog-Stim-N-B and Prevention-N-E. Methodology. Research work was carried out in the conditions of the center of the canine service of the Ministry of Internal Afairs and the Aibolit veterinary clinic in Cheboksary during 2016-2020. For research work, 3 groups of dogs of one breed were formed at the age of 2 months, 5 heads in each group. In order to prevent immunodefciency of the body, dogs of the 1st experimental group were injected intramuscularly with the biopreparation Prevention-N-E at a dose of 0.1 ml/kg of live weight twice on the 61-63 and 68-69 day after birth, dogs of the 2nd experimental group at the same dose and at the same time injected with the biopreparation Dog-Stim-N-B. Results. Two-fold intramuscular injection to service dogs of the 1st and 2nd experimental groups of DogStim-N-B and Prevention-N-E biologics on the 61-63 and 68-69 day after birth increased blood hemoglobin concentration compared to 2 control.0-5.0 and 4.0-15.0 g/l, number of red blood cells - by 1.09 and 1,10 × 1012/l, the concentration of total protein - on 2.8-5.4 and 2.8-8.2 g/l, including the albumin fraction - on 2,5-3.4 and 3.3-4.3 g/l a γ-globulin - by 0.8-2.4 and 0.3-2.9 g/l. In addition, biologics contributed to an increase in plasma lysozyme activity and bactericidal activity of dog blood serum, which indicates an activation of the humoral link of the body's nonspecifc resistance. Conclusion. Biopreparation Dog-Stim-N-B and Prevention-N-E activate hematopoiesis, cause physiological eosinophilia, neutrophylopenia with neutrophilic nucleus shift to the right and lymphocytosis, stimulate protein exchange, synthesis of albumins and γ-globulins, increases cellular and humoral factors of non-specifc resistance

Abstract Background and aims: Diabetes mellitus (DM) is a risk factor for pulmonary tuberculosis (TB), increasing the risk of progression of latent tuberculosis infection (LTBI) to active TB threefold, threatening the TB control, especially in developing countries. The aim of this study was to assess active and latent TB infection frequency in patients with DM. Material and methods: There were enrolled in this study 503 adult DM patients. Active TB screening was performed through anamnestic data, clinical examination and chest X-ray and latent TB infection screening was evaluated using the tuberculin skin tests (TST). Results: A number of 63 (12.5%) patients had type 1 DM and 440 (87.5%) had type 2 DM. Personal history of TB was present in 21 (4.2%) subjects, 5 (8.1%) with type 1 DM and 16 (3.6%) with type 2 DM. The TST was positive in 258 (51.5%) patients and 54 (10.7%) presented cough for more than two weeks at the time of examination. The chest X-ray revealed suggestive lesions for active TB in 4 (1%) subjects and lesions of inactive TB in 90 (22.4%) subjects. Conclusions: TB screening must receive proper attention in patients with DM, being essential for diagnosis in those with nonspecific symptoms.

Objective: Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is reported in the literature ranging from 1 to 14.2%. The aim of the present study was to assess the impact on patient’s quality of life and symptoms of Flower pollen extract in association with vitamins (Deprox 500®) in comparison with Serenoa repens 320 mg (Permixon 320 mg® by Pierre Fabre) in patients with CP/CPPS. Methodology: All consecutive patients, with a diagnosis of CP/CPPS, referred to our center from January to August 2016, were screened to be enrolled in this single-center, randomized, controlled trial. The main outcome measure was the evaluation of IPSS/NIHCPSI (International Prostatic Symptom Score/NIH-Chronic Prostatitis Symptom Index) score variation and the assessment of the quality of life and symptoms at the end of the therapy. The second outcome measure was the evaluation of the comorbidity role in the CP/CPPS therapy. 63 patients were analyzed; patients were randomized into two groups: 29 patients were treated with Deprox 500® 2 tablets/day for 6 weeks and 34 patients with Serenoa repens 320 mg, 1 tablet/day for 6 weeks. Results: The mean score variation for IPSS was -12.7 ± 4.3 in the Deprox 500® group and -7.8 ± 4.7 in the Serenoa repens group (p=0.0005) while for NIH-CPSI was -17.3±3.1 in the Deprox 500® group and -13.6±4.8 in the Serenoa repens group (p=0.0016). By accounting only the symptoms part of NIH-CPSI questionnaire, the mean score variation reported was -11.5±2.5 in the Deprox 500® group and -9.02±4.0 in the Serenoa repens group (p=0.009321). Furthermore, analyzing the comorbidity subgroups, in patients with hypertension, the mean IPSS score variation was -14.3±3.2 in the Deprox 500® group and - 9.02±4.0 in the Serenoa repens group. Conclusion: In conclusion, in patients with CP/CPPS, Deprox 500® improves IPSS and NIH-CPSI scores up to 74.5% and 84.5% respectively. Furthermore, in patients with hypertension, the antioxidant effect of Deprox 500® reduces the mean IPSS score of 82.7%.

Data on the distribution of accumulation with elevation were used to calculate ablation, internal accumulation, annual mass balance and glacier runoff for the Tien Shan glaciers with a total area of about 15 500 km2. The altitudinal profile of normalized ablation is approximated by an exponential curve. Mass-balance components and glacier runoff are calculated for the whole possible range of glacier equilibrium-line positions in the major river and lake basins of the Tien Shan.For steady state it was found that the equilibrium line rises from 3600 m in western areas to 4400 m in the east, whilst the accumulation area ratio and glacier runoff increase eastward from 63% to 71%, and from 600 to 1200 mm, respectively. Losses of meltwater runoff for internal accumulation average 7% (5–11%).In abnormally warm years, mass balance may reach –2300 mm w. e. in the west and –855 mm in the east and in the internal Tien Shan (Khan Tengry massif). Glacier runoff volume in those years has been estimated at 40 km3 year–1, which is 2.5 times as large as for the steady state.
