The results from a comparative ultrastructural study of spermiogenesis in 6-, 10-, 14- and 17-month-old sterile t6/tw32, and fertile T/t6, T/tw32 and BALB/c, mice are reported. The studies show that all of the males contained the same types of defective spermatids and that defects were not limited to specific spermatid stages. Younger males had fewer abnormal spermatids than older males of the ...

First-principles calculations are performed to identify the pristine and Si doped 3D metallic T6 carbon structure (having both sp2 and sp3 type hybridization) as a new carbon based anode material. The π electron of C2 atoms (sp2 bonded) forms an out of plane network that helps to capture the Li atom. The highest Li storage capacity of Si doped T6 structure with conformation Li1.7Si1C5 produces ...

BACKGROUND Polypeptide N-acetylgalactosaminyltransferases (GalNAc-Ts) are important glycosyltransferases in cancer, but the clinical role of its individual isoforms is unclear. We investigated the clinical significance and survival relevance of one isoform, GalNAc-T6 in lung adenocarcinoma after curative resection. RESULTS GalNAc-T6 was identified in 27.8% (55/198) of patients, and statistica...

Shubhra was conducted in Research Field, Department Horticulture, Sam Higginbottom University Agriculture, Technology Sciences, Prayagraj, during winter season (2022-23). experiment laid out Randomized block design (RBD). There are 9th treatment combination ...

Abstract The purpose of this experiment was to determine the impact that applying biostimulant Boiohealth and spraying dry bread yeast suspension would have on chemical components leaves total yield two different varieties kohlrabi during autumn 2021-2022 at University Karbala’s College Agriculture. included factors, first factor includes eight fertilizer combinations, its without addition (T1)...

Wastewater dissolved organic matter (DOM) from different processing stages of a sewage treatment plant in Xiamen was characterized using fluorescence and absorption spectroscopy. Parallel factor analysis modeling of excitation-emission matrix spectra revealed five fluorescent components occurring in sewage DOM: one protein-like (C1), three humic-like (C2, C4 and C5) and one xenobiotic-like (C3)...

The surface layer machined after electrical discharge machining (EDM) is different from it traditional methods, and studying the structure by this method will contribute significantly to selection of finishing methods. In study, SKD61 steel EDM using copper (Cu) electrode was analyzed. Technological parameters including current (Ie), pulse on time (Ton), off (Tof), voltage (Ue) were used in stu...

Particle size distribution (size-range 3–900 nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in September–November 2002. The study investigates the contribution from urban versus regional sources of particle number and mass concentration. The total particle number (ToN) and NOx are well correlated...

BACKGROUND Hemodynamic disturbances are common during continuous epidural anesthesia in elderly patients undergoing total hip arthroplasty. This study aimed to investigate the effects of methoxamine on the intraoperative hemodynamics in elderly patients undergoing total hip arthroplasty under epidural anesthesia. MATERIAL AND METHODS This prospective study included 150 elderly patients underg...
