Trouble Having a Baby? It Might Be Male Infertility
Infertility is often viewed as a woman's problem but when a couple has trouble conceiving, there's a good chance it's related to male factors -- in fact, that's the case 40-50 percent of the time. That's why the male partner should be part of any couple's fertility assessment. Not only is male infertility more common than most people realize, male factors are the sole reason for a couple's inability to have a baby 15 percent to 25 percent of the time. While some reasons for male infertility are well understood, at least 50 percent of problems are due to unknown factors. Male infertility can occur when men have a less than normal semen analysis because of a reproductive problem such as testicular damage that reduces their chances of getting their partner pregnant and affects development and live birth. Problems with sperm range from producing too few (low sperm concentration or count), movement (low motility) issues or sperm that are not shaped properly (abnormal morphology). Or, there may be physical problems such as a blockage of the reproductive tract that prevent sperm from getting out. Besides a physical exam and medical history, there are a variety of diagnostic tests that may be used to identify problems and hopefully lead to a solution. These include semen analysis which will look at the quality and quantity of sperm including the volume of semen, the number of sperm, whether they move and are shaped correctly. The semen must be tested within an hour of collectio...

Butola, Sahil MalhotraAbstractWith increasing demand for novel and potent antimicrobial agents to combat cross-infections and infectious diseases, silver and copper based nanoparticles (NPs) deposited over supports such as montmorillonite (MMT) are playing a crucial role in shaping the current research scenario. Although materials based on Ag NP and Cu NP on MMT have been reported, its toxicological properties on human cell lines have not been accounted for. This paper reports a comparative st...

In this paper, we propose an automated pulmonary nodule detection algorithm, denoted by NODULe, which jointly uses a conventional method for nodule detection and a deep learning model for genuine nodule identification. Specifically, we first use multi-scale Laplacian of Gaussian (LoG) filters and prior shape and size constraints to detect nodul...

CONCLUSIONS Our finding revealed that resistance against amphotericin B, itraconazole, ketoconazole, posaconazole, and fluconazole can be observed in C. albicans.

The findings by Columbia University add to the large body of evidence linking factors like education, income and access and affordability of care to worse survival rates for cancer.

WeissAbstractHighly sensitive detection of heat denatured Herceptin® (trastuzumab), an important monoclonal antibody used in breast cancer therapeutics, is demonstrated using transverse magnetic (TM) mode suspended microring resonators (MRRs). The suspended MRRs are surface functionalized with a single chain fragment variable (scFv) recombinant antibody molecule (designated 2B4) that enables selective capture of denatured Herceptin...
