Facilitative hexose transporter expression was compared in rat and human testes. In rat testis, only GLUT1 and GLUT3 proteins were expressed. By contrast, human testis expressed GLUT1 and GLUT3 in addition to GLUT5. Immunocytochemical studies showed that GLUT3 was expressed in all cells of the seminiferous epithelium of rat testis, including sperm. In human testis, GLUT3 was expressed exclusively in cells juxtaposed to the lumen of the seminiferous tubule and ejaculate sperm, a pattern of expression that was identical to that of GLUT5.

ABSTRACT A single injection of ethane-1,2-dimethanesulphonate (EDS; 100 mg/kg) selectively destroys Leydig cells in the testis of the adult rat; however, unconfirmed reports indicate that Leydig cells in the immature rat are not affected. In this study the effect of EDS was examined 2 days after treatment of rats aged 20, 25 or 35 days. There was a large reduction in the in-vitro binding of 125I-labelled human chorionic gonadotrophin (hCG) to the homogenates of testes from EDS-treated immature rats. EDS reduced the testosterone content of the testes at all ages studied, but 2 days after inject

ABSTRACT: Adult Sprague‐Dawley“ male rats, weighing about 350 g, were rendered cryptorchid by suturing the testes to the lateral abdominal wall. Twenty‐eight days later, cryptorchidism resulted in a significant decline in testis weight and suppressed spermatogenesis. The ventral prostate was significantly smaller in cryptorchid rats. There was no significant difference in serum testosterone levels between the normal and cryptorchid rats. Charcoal‐stripped aqueous extracts of the testis from intact and cryptorchid animals were tested on primary cultures of rat prostatic stromal cells. Cultures

The testis has been suggested as an immune privileged site for islet transplantation. The present study evaluated this hypothesis by transplanting islets from Wistar Furth rats into (a) the testes; (b) the subcapsular space of the kidneys; or (c) the cryptorchid abdominal testes of streptozotocin-induced diabetic Swiss ND4 mice. Transplantation of 800 rat islets into the cryptorchid testes normalized blood glucose for 9.3 ± 1.4 (Mean ± SD) days, not significantly different from that of the scrotal testis site (12.4 ± 1.3), or when the subcapsular space of the kidneys was used (11.5 ± 1.2).

ABSTRACT: The efficacy and toxicity of a new method for chronic direct intratesticular drug infusion were assessed in a rat model. To this end, luteinizing hormone (LH) or buffer was infused via mini‐osmotic pumps for 14 days directly into the parenchyma of Copenhagen rat testes. The surgical manipulation and direct infusion of buffer did not have any apparent adverse effect upon either spermatogenesis or steroidogenesis as measured by testis weight, homogenization‐resistant spermatid count, and in vitro response of the testes to a maximally stimulating concentration of LH.

In the past two decades, testicular tissue grafting and xenografting have been well established, with the production of fertilization-competent sperm in some studies. However, few studies have been carried out to observe the development of grafted prepubertal testicular tissue of rats and compare the biological differences between in situ testis and grafted testis. In this study, we established the prepubertal testicular tissue xenografting model using a 22-day-old rat and evaluated certain parameters, including testicular histology, testosterone production, and ultrastructure of the grafted t

Homologous genetic recombination is a central feature of meiosis in most sexually dividing organism. It leads to the establishment of new linkage relationships between genes and is crucial for the successful completion of meiosis. It is also necessary for a variety of important cellular events like immunoglobulin rearrangement, repair of chromosome damage, gene amplification, gene expression and sister chromatid exchange. Knowledge of the mechanisms of homologous recombination has come from extensive genetic studies on fungi. These studies have led to the formulation of various models which

Abstract Mercury is a naturally occurring component present in varying concentrations in natural gas fields all over the world. Liquid metal embrittlement (LME) involves penetration of a liquid metal into a solid metal that leads to brittle fracture.

Most of the tests are performed by use of small-scale specimens with size typically in the range of a few inches to tens of inches (1 in = 25.4 mm). There are numerous test labs capable of performing most small-scale tests. These tests can be performed effectively under a variety of conditions, e.g., test temperature, strain rate, and loading configuration. More importantly, most routine small-scale tests are performed in accordance with national and international standards, en

In 1998, a multi-year project to develop a working prototype instrument module for natural gas energy measurement was initiated. The module will be used to retrofit a natural gas custody transfer flow meter for energy measurement, at a cost an order of magnitude lower than a gas chromatograph. Development and evaluation of the prototype energy meter in 2002-2003 included: (1) refinement of the algorithm used to infer properties of the natural gas stream, such as heating value; (2) evaluation of potential sensing technologies for nitrogen content, improvements in carbon dioxide measurements, an

Uniaxial tensile tests were conducted on American Society for Testing Materials International (ASTM) A992 and A572 Grade 50 steels at increasing strain rates to determine the material strength properties of structural members subjected to dynamic loadings. The increase in dynamic yield strength and ultimate tensile strength was determined to update design criteria within UFC 3-340-02, which are currently limited to ASTM A36 and A514 steels. The proposed updates will provide the necessary information required to design blast-resistant structures utilizing modern-day structural steels. The dynam

Experimental work was conducted on two girth welds in large diameter steel pipes. By a proper selection of welding consumables, yield strength mismatch was obtained from 5 to 12% undermatching and 45% overmatching. The girth welds were non-destructively tested using the time of flight diffraction technique by three NDE companies. The verification of the detection and sizing capabilities of TOFD inspection techniques has shown that the performance levels varied widely. This finding confirms the need to validate the NDE techniques. Tensile specimens, Charpy and CTOD specimens, and curved wide pl

Cracking is a primary mode of failure for asphalt concrete (AC), resulting in road damage and deterioration, and leading to an increase in road hazards and fatalities. Studying the fracture behavior of AC is an effective way to learn how to best enhance their cracking resistance. To do this, the indirect tensile cracking laboratory test (IDEAL-CT) was developed and used to assess the AC cracking behavior by defining a unique index that allows the ranking of different mixes’ cracking resistance. The sensitivity of the test results to the test parameters is needed to monitor the test’s performan

Conducting small asphalt repairs on airfields in remote locations can be technically and logistically challenging. An alternative to cold patch products is using an engineered polymer binder (EPB) mixed with recycled asphalt pavement (RAP). This paper presents the results of a laboratory evaluation of EPB with both wet and dry RAP. Compacted specimens were tested for rut resistance, indirect tensile strength (ITS), and Cantabro mass loss (ML). The results indicate that RAP mixed with EPB exhibited substantial rut resistance with ITS and ML similar to that of conventional dense-graded asphalt.
