Men with congenital absence or bilateral partial aplasia of vas deferens, or those with failed or surgically unreconstructable obstructions or azospermic men with testicular failure or genetic cause can now be treated by using sperm retrieval techniques in conjunction with in vitro fertilization/intra cytoplasmic sperm injection (ICSI/ IVF). These techniques are: Microsurgical epididymal sperm ...

In this paper, we have synthesized two novel diketopyrrolopyrrole (DPP) based donor–acceptor (D–A) copolymers poly{3,6-dithiophene-2-yl-2,5-di(2-octyl)-pyrrolo[3,4-c]pyrrole-1,4-dione-alt-1,5-bis(dodecyloxy)naphthalene} (PDPPT-NAP) and poly{3,6-dithiophene-2-yl-2,5-di(2-butyldecyl)-pyrrolo[3,4-c]pyrrole-1,4-dione-alt-2-dodecyl-2H-benzo[d][1,2,3]triazole} (PDPPT-BTRZ) via direct arylation organo...

In real world problems, one is often faced with the problem of multiple, possibly competing, goals, which should be optimized simultaneously. These competing goals give rise to a set of compromise solutions, generally denoted as Pareto-optimal. If none of the objectives have preference over the other, none of these trade-off solutions can be said to be better than any other solution in the set....

In general, the man’s response to infertility has been viewed as taking less of an emotionally than his partner’s. While the findings on quality of life (QoL) of infertile women have shown mainly agreement, this seems not to be the case in men. Studies on men’s QoL have resulted in inconclusive findings. It is clear that male infertility is one of important issues in men’s health as it could al...

The ICSI has become method of choice to achieve fertilization. Fertilization is possible in cases in which the sperm motility and ability to penetrate the zona pellucida are impaired. Injection is possible with sperm obtained from ejaculation, microsurgical epididymal sperm aspiration (MESA), percutaneous epididymal sperm aspiration (PESA), or testicular sperm extraction (TESE). In addition, in...

BACKGROUND Observational studies and clinical trials are increasingly highlighting significant associations between periodontitis (chronic, infectious, inflammatory disease affecting tooth supporting tissues) and rheumatoid arthritis (chronic systemic autoimmune disease). OBJECTIVE The aim of the study was to describe the dental, periodontal and oral prosthetic status of outpatients with Rheu...

Infertility is a common yet complex problem affecting approximately 10-15% of couples attempting to conceive a baby. Especially, 40-50% of these factors are known as male-related disorders. Unlike female infertility, the cause of which is often easily identified, diagnosing male factors can be difficult. Male infertility is due to low sperm production, abnormal sperm function or blockages of sp...

Utafiti huu ulichunguza suala la ukahaba katika riwaya ya Nyota Rehema (Mohamed S.Mohamed) na Ndoto Almasi (Ken Walibora). Kitendo cha kimesababisha mashaka mengi sana maisha mwanadamu kama vile kupoteza ujira, uharibikaji wa ndoa, maradhi zinaa, vifo, kukata tamaa utengano miongoni mwa wanajamii. Madhumuni utafiti yalikuwa ni: kubainisha usawiri wahusika makahaba Almasi; kuchunguza sababu zina...
