Abstract:
Undescended testis or cryptorchidism is a common genital problem in boys. Non palpable testis represents 25% of all undescended testis. Non palpable testis presents a unique diagnostic and therapeutic problem. Non palpable testis should be treated to enhance future chances of fertility and to place the testis at a site where it can be easily palpated because such a testis has an increased susceptibility to malignant degeneration. Aims: • Toestablishdiagnosticefficacyandaccuracy in identifying clinically non-palpable testis. • To establish therapeutic role of Open and laparoscopic management of non-palpable testis. Methods and Material: Between 2015 and 2019, 25 boys with 28 clinically non-palpable testis, aged 16 months to 65 years, underwent operative intervention in a single surgical unit at our institute. Out of the 25 patients, 22 had unilateral (11 leftsided, 11 right-sided) and three had bilateral non palpable testis. The testis was considered non palpable after thorough clinical examination, ultrasonography and examination under anaesthesia failed to detect it. Keywords: Nonpalpable Testis

Abstract:
Undescended testis is one of the most common congenital anomalies in newborns. Incidence of this is anywhere between 1.6% and 9.0%. The incidence dramatically drops to 0.9-1.8% at 3 months of age. This is due to the spontaneous descent of the testes. The complications of undescended testes are infertility and malignant transformation. A 29-year-old unmarried male patient came to the hospital with complained of absent of left testis within scrotal sac since birth and a left inguinal swelling since 1 year with no other complaints. On examination, the left scrotal sac was empty. The right side scrotum was normal and testis was palpable within scrotal sac. On USG, examination findings were confirmed Left testis seen in relation to lower pole of left kidney in left inguinal region with normal echo texture s/o left ectopic testis. Left kidney in pelvic region at paramedian location with hilum facing anteromedially s/o left ectopic kidney. Early diagnosis and surgical intervention is key so as to preserve the undescended testis and prevent malignant change or infertility problems. It is imperative that all tests be done to assess kidney function.

Abstract:
Objectives. Ascending testis or acquired undescended testis develops in approximately 30% of cases of retractile testis, and orchiopexy is recommended for these cases. This study aimed at assessing the intraoperative anatomical findings of ascending testis and acquired undescended testis in search of better management for retractile testis. Methods. We retrospectively collected data of patients with confirmed diagnosis of retractile testis between February 2012 and November 2021. Orchiopexy was performed for cases with ascending testis and for patients with increasing difference of right and left testicular volume. The site of gubernaculum attachment and patent processus vaginalis were evaluated during surgery. Results. A total of 119 testes in 71 patients with retractile testis were included in this study. Sixteen retractile testes in 12 patients (17%) underwent orchiopexy. The weight at birth was significantly higher, and bilateral retractile testes were significantly more common in the follow-up group than in the surgical intervention group. In the surgical intervention group, the abnormal site of gubernaculum attachment was found in 12 out of 16 testes (75%), and patent PV was found in nine out of sixteen testes (56%). Sites of gubernaculum attachment in testes with patent PV were significantly higher than in sites with closed processus vaginalis, and all testes with patent processus vaginalis had abnormal site of gubernaculum attachment. Conclusion. Patients with ascending testis and acquired undescended testis have clinical features and intraoperative abnormal findings similar to a cryptorchidism. Therefore, our surgical indication for retractile testis is considered appropriate.

Abstract:
Mammalian sex is determined by the presence or absence of Sry. This gene, located on the Y chromosome, promotes the development of a testis from the biopotential gonad by initiating a transcriptional programme that results in Sertoli cell formation. SRY is required to reach a specific threshold level during a critical time-period in order to induce the testicular differentiation pathway. We have previously shown that XY mouse embryos lacking Growth arrest and DNA damage inducible 45 gamma (Gadd45g) exhibit gonadal sex reversal due to a delay in Sry expression. Efforts to study the role of GADD45γ in sex determination have been stymied by the lack of a working antibody. As an alternative, I have produced a BAC transgene produces a similar expression profile to endogenous Gadd45g. This BAC was also shown to rescue the sex reversal found in B6-YPOS gonads, though further research is required to understand the molecular mechanisms through which this occurs. As a result, this BAC was chosen for modification using BAC recombineering to contain the sequence for a poly-His/FLAG epitope tag. Though this edited BAC was generated successfully, no transgenic lines have yet been produced. Members of the Gadd45 family have previously been associated with active DNA demethylation. Assuch, I have conducted whole genome bisulphite sequencing on DNA from XY wild-type, XX wild-type and XY Gadd45g-/- embryos at the 18 tail somite stage, where Sry expression is at its peak. Gadd45g and Sry are only expressed in the somatic cells of the gonads, which have been purified through fluorescence-activated flow cytometry using the transgenic line Sf1-EGFP. Due to the low number of cells that are purified from the embryonic gonad at this stage, sequencing libraries were generated using post-bisulphite adaptor tagging (PBAT). Analysis of the acquired sequences revealed that there are no significant differences between the methylomes of XY wild-type, XX wild-type and XY Gadd45g-/- mutant gonadal somatic cells. It therefore appears that GADD45γ does not have a role in establishing the methylome at this particular stage of sex determination.

Abstract:
The obligatory role of pituitary luteinizing hormone (LH) and follicle stimulating hormone (FSH) in the control of testicular function is well established. However there is increasing experimental evidence, largely in the rat, that quantitatively normal spermatogenesis not only requires an adequate local supply of testosterone but also the complex interactions between the various cellular components within the seminiferous tubules and interstitial compartments of the testis. The critical role of paracrine mechanisms in the testis may be reflected by the defective spermatogenesis in idiopathic male infertility where systemic levels of LH, FSH and testosterone are normal or elevated. Thus to further our understanding of the hormonal control of spermatogenesis and to define possible aetiological mechanisms in the infertile man, the study of paracrine mechanisms in the human testis is of paramount importance. The approach to study paracrine mechanisms in the human testis was to establish in vitro techniques whereby individual components of the testis were isolated and specific functional markers defined so that their subsequent interaction could be further studied in vitro. At the same time, the delineation of these 'local' parameters were related to the overall functional states of the testis as defined by circulating levels of LH, FSH, testosterone and the histological assessment of spermatogenesis. Testes were obtained at orchidectomy for prostatic carcinoma and from post mortems carried out within 15 hours of death. Methods were established to examine the effect of intratesticular levels of testosterone and systemic levels of LH, FSH and testosterone on quantitative measures of spermatogenesis. For this purpose a simple technique which involved enumeration of spermatid nuclei in fixed testicular homogenates to determine daily sperm production was adopted. Daily sperm production in this group of ageing testes was generally lower than has been observed previously for younger men. Although intratesticular levels of testosterone varied widely there was no indication of an intratesticular deficiency of testosterone as a critical factor in subnormal spermatogenesis in the ageing testis. Inhibin, a peptide marker of Sertoli cell function was measured in human testicular extracts using a sheep pituitary cell bioassay. Inhibin bioactivity was shown to be present in the human testis. The testicular inhibin content did not seem to bear any relationship to FSH implying that the role of inhibin in the testis may be somewhat different to the classical concept of FSH feedback. A technique for the routine isolation of human Leydig cells was established. Human Leydig cells purified by Percoll density centrifugation were highly responsive to hCG, although sensitivity and receptor number were significantly lower compared to the rat. This system was used to test for the effects of putative paracrine factors on human Leydig cell function. In conclusion, a number of in vitro techniques have been established and validated which provide a basis for future investigation of seminiferous tubule and Leydig cell function in the human testis.

Abstract:
Mestrado em Biomedicina Molecular
T-complex testis expressed protein 1 domain containing 4 (TCTEX1D4) é uma cadeia leve de dineina identificada como sendo uma proteina que interage, no testículo humano, com a fosfoproteina fosfatase 1. As funções específicas da TCTEX1D4 ainda são desconhecidas e identificar as suas proteinas interactoras pode ilucidar sobre as funções desta. Foi aplicado o método de dois híbrido de levedura com o intuito de identificar o interactoma da TCTEX1D4. Foram obtidos 494 clones positivos, dos quais 86 foram identificados correspondendo a 44 diferentes proteinas. Uma análise in silico das características funcionas de todas as proteinas identificadas revelou que as proteinas que interagem com a TCTEX1D4 apresentam funções tão diversas como ligação a iões, ligação ao DNA e actividade peptídica. Também foram obtidas os padrões de expressão em diversos tecidos da base de dados UniGene. Duas proteinas que interagem com TCTEX1D4 são específicas de testículo enquanto 5 são enriquecidas nestes tecido. A rede de interação da TCTEX1D4 foi construída no Cytoscape e combinando os padrões de expressão foi possível identificar possíveis complexos proteicos da TCTEX1D4 específicos ou enriquecidos no testículo. Os complexos TCTEX1D4/TCTEX1D2 e TCTEX1D4/CRISP2 foram caracterizados mais profundamente, revelando que a TCTEX1D4 pode estar envolvida na reação acrossómica, mobilidade do espermatozoide e na interação célula-célula. Em conclusão as funções da TCTEXD4 ainda são desconhecidas mas a identificação e caracterização do seu interactoma ajuda a revelar as suas possiveis funções.
T-complex testis expressed protein 1 domain containing 4 (TCTEX1D4) is a dynein light chain that was identified as a phosphoprotein phosphatase 1 interacting partner in human testis. The specific functions of TCTEX1D4 in testis are still unknown and identification of TCTEX1D4 interacting proteins can ilucidate possible functions of this protein. A yeast two hybrid approach was undertook to identify the TCTEX1D4 interactome. We obtained 494 positive clones from which 86 clones were identified corresponding to 44 different proteins. An in silico analyzis was performed for all proteins identified. In silico functional characterization of TCTEX1D4 interactome reveald its diverse in cellular functions ranging from proteins with ion binding function to DNA binding and peptidase activity. Also a tissue expression distribution was obtained from UniGene database and 2 specififc testis and 5 testis enriched TCTEX1D4 interacting proteins were identified. A TCTEX1D4 network was constructed n Cytoscape and combining tissues expression profiles we were able to identified possble TCTEX1D4 protein complexes specific or enriched in testis. Two TCTEX1D4 protein complexes TCTEX1D4/TCTEX1D2 and TCTEX1D4/CRISP2 were further studied revealing that TCTEX1D4 may be involved in acrosome reaction, sperm motility and cell-cell interaction. In conclusion TCTEX1D4 is still known but identification and characterization of its interactome can help unveil its putative functions.

Abstract:
Optical tomography and NIR spectroscopy are potential methods to improve the diagnosis of testicular pathologies. To evaluate the methods clinically we developed a special measurement device with the capability of spatially resolved laser spectroscopy and optical tomography of the testis. Simple spectroscopy is primarily used to obtain global tissue optical properties of the testis and to find correlations of optical parameters with type and stage of certain pathologies. Optical tomography is applied to visualize spectral contrasts in limited tissue volumes, such as tumors. In the course of the study we will determine whether NIR techniques posses the required specifity and sensitivity to give additional quantitative information about tissue perfusion parameters and to serve for a tumor differentiation.

Abstract:
The asphalt industry is moving towards performance-based methods for asphalt mixture design. The Federal HighwayAdministration (FHWA) is supportive of state departments of transportations (DOT) adopting index and predictive performance tests, especially those making use of the Asphalt Mixture Performance Tester (AMPT). The FHWA is therefore encouraging state DOTs to gain experience with the requirements of the procedures and analysis tools for Balanced Mixture Design (BMD). The main objective of this study is to evaluate fatigue cracking on three INDOT mainline pavement projects that have asphalt mixtures designed by the Superpave 5 mixture design, and to better understand the fundamental engineering testing capabilities of the AMPT. A total of four Superpave 5 asphalt mixtures were collected and tested from the three projects. The viscoelastic characteristics and fatigue behavior of plant-mixed, laboratory compacted (PMLC), laboratory-mixed, laboratory compacted (LMLC), and plant-mixed, field compacted (PMFC) specimens were assessed according to the AASHTO TP-132 and AASHTO TP-133 test methods. Two AMPT machines (IPC Controls and PaveTest) were used to conduct the dynamic modulus tests, while all fatigue tests were performed using a PaveTest AMPT. The raw data were analyzed using the FlexMAT software. The dynamic modulus and cyclic fatigue test results indicate that AMPT testing can be used to effectively evaluate INDOT asphalt mixtures during the mixture design and production phases. However, to do so, detailed planning and effective training are needed to help ensure the successful completion of AMPT testing.

Menke, Amelia, Sally Shoop, and Bruce Elder. Use of a portable friction tester on snow and ice pavement. Engineer Research and Development Center (U.S.), February 2022. http://dx.doi.org/10.21079/11681/43380.

Full text
Abstract:
The objective of this project was to determine if portable friction testers could be used for friction measurements on compacted snow and ice surfaces. First, the effect of cold temperatures on the operation, consistency, and accuracy of commercially available portable pavement friction measuring tools was evaluated. Tests entailed a series of experiments in a controlled cold room environment. Two portable fixed slip continuous measurement devices and one deceleration spot measurement device were evaluated. The controlled temperature testing determined how ambient temperature and duration of exposure can affect results, but that with care, the devices could be operated in conditions as cold as ˗25°C. This was followed by using one of the devices on outdoor testing on snow, ice, and asphalt surfaces and compared the portable tester to the well-known SAAB vehicle runway friction tester. Results showed good agreement between the portable tester and the SAAB Friction tester, providing validation for the operational use of a portable tester on frozen surfaces.

Amend. PR-186-133738-R01 Procedure for Determining Lower Bound Yield Strength of Pipe from Hardness Data. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), July 2014. http://dx.doi.org/10.55274/r0010847.

Full text
Abstract:
This project is a JIP project with the overall objective of demonstrating that hardness data from randomly selected pipe samples could be used to determine the lower bound YS of an entire pipeline segment at a quantified confidence level, and that results would be conservative in comparison to results determined using the methods currently described in 49 CFR Part 192 and 195. Three different types of field portable hardness testers and a laboratory Rockwell B tester were used on 50 pipe sample. The hardness testing using field portable testers was performed in accordance with ASME CRTD-Vol. 91. The hardness test results were converted to a calculated lower bound YS values using the correlations described in ASME CRTD-Vol. 57. The calculated lower bound YS was compared to the results of standard API 5L tensile tests. In addition, the metallurgical attributes of each pipe were characterized to determine if certain subsets of pipes produced better (or worse) correlations of lower bound YS calculated from hardness data to YS determined from tensile tests. The results showed that hardness data can be used to determine conservative values of lower bound YS using a range of different confidence levels.

Abstract:
This project is a follow up to the project titled "Effects of Tensile Loading on Remaining Strength of Corroded Casing." The objective is to test additional samples of corroded casing that will fail at typical storage well operating pressures and transfer the developed technology to MFL vendors for use in storage fields. A test matrix of 13 specimens was developed and tested. The test specimens consisted of natural corrosion and machined defects. Prior to testing: � the specimen material was characterized with tensile, Charpy V-notch, hardness, and chemical tests and � the test specimens were shipped to 2 MFL vendors for logging. The results of the testing and MFL characterization are summarized in this report.

Full text
Abstract:
Pump suction piping testing was performed to measure the influence on pump performance and mechanical operation, and also provide a benchmark for comparing, verifying and improving CFD modeling techniques. Testing was performed in Sulzer's pump test laboratory, in Winterthur Switzerland, using a single stage double suction model pump a with similar specific speed and design as used in many crude oil pipeline installations. Testing included a baseline test with a straight pipe with a flow straightener at the pump suction and two arrangements with pipe elbows directly at the pump suction. All tests were performed with mineral oil at viscosities ranging from 90 to 500 cSt. Pump performance as well as several static and dynamic measurements were taken, including static pressure measurements along the suction pipe, dynamic pressure measurements at the pump suction and discharge, pump axial thrust and displacements and pump torque. The tests with elbows at the pump suction are compared to the baseline test results. This work will benefit the liquids pipeline station designers and operators and also CFD analysts by providing actual tested comparisons and benchmark measurements.

Abstract:
This report describes the results of technical analysis, field tests, and laboratory tests that were performed for LED highway lighting options by the Energy Efficiency and Reliability Center (EERC) at Purdue University Northwest for the Indiana Department of Transportation (INDOT). This effort was conducted over the past 3 years to evaluate and test the technology and viability of using modern highway lighting technology to enhance energy efficiency, safety, security, and economic development of communities and roadways. During the testing period there was a continuous discussion between INDOT and EERC regarding the laboratory and field testing of INDOT approved luminaires submitted by vendors. There were multiple discussions with INDOT and vendors regarding the individual details and issues for the 29 luminaires that were tested. A comparison study was conducted by EERC of the various alternatives and comparison to currently installed luminaires. Data was collected for field tests of the luminaires by EERC and INDOT personnel for the luminaires. Field data was evaluated and compared to lighting models using vendor supplied ies data files. Multiple presentations were made at 3 separate Purdue Road Schools regarding the results and procedures of the testing program by EERC in conjunction with INDOT. A total of 22 final reports, considered confidential by INDOT, for individual vendor luminaires have been prepared as part of this effort. These reports were submitted sequentially to INDOT as testing was completed during the course of this effort. A total of 29 luminaires were tested. Some luminaire testing was terminated during testing due to design issues or vendor requests. All testing was summarized in the INDOT specification sheet attached to each report. Observations regarding the consistency of the supplied test luminaire with the requirements of Section 7.2 of the INDOT test procedure “Procedure for evaluation and approval list requirements for solid state ballasted luminaires ITM 957-17P” is provided in the Appendix to the report for each luminaire. Details regarding how these tests were performed and the respective associated evaluation of performance and reliability are provided in the report. This effort included: consideration of published and vendor information; appraisal of products consistent with national industry standards; review of physical design, thermal performance; laboratory testing of photopic performance, reliability, life cycle data and characteristics, and power characteristics; technical and probabilistic risk studies; and field testing and analysis of LED light sources including comparison to currently installed conventional light sources. Assistance in preparing INDOT standards for highway lighting was provided on multiple occasions.
