Partial or complete fertilization failure after IVF was reported in 5-10% of cycles. Total fertilization failure in patients with normal sperm parameters is rare but very stressful incident after IVF. To rescue the IVF cycles after total fertilization failure, ICSI of unfertilized oocytes after initial insemination has been reported.We reviewed a 2 years experience of rescue ICSI and analyzed t...

During fertilization, eggs undergo a temporary rise in the intracellular concentration of free Ca(2+) ions. Using the membrane permeable acetoxymethylester of the fluorescent calcium indicator dye Fura-2, Fura-2 AM, the Ca(2+)-signal at fertilization was not detectable in eggs of the sea urchin Psammechinus miliaris. However, after treatment of the eggs with Fura-2 AM in combination with MK571,...

Tagetes erecta (T. erecta) is an herbaceous species, having wide ethno medicinal and traditional uses. It demonstrates different pharmacological activities like antioxidant, antimicrobial and anti depressant. The present study deals with the estimation of antioxidant properties of four solvent extracts of flowers of T. erecta. The study aims to discover potent extracts as a novel source of natu...

BACKGROUND In vitro fertilization (IVF) of eggs by frozen and thawed C57BL/6J mouse sperm is inhibited by dead sperm and enhanced by preincubation of the sperm in calcium-free medium. In other species, the presence of sperm killed by freezing and thawing has been associated with the generation of hydrogen peroxide. METHODOLOGY/PRINCIPAL FINDINGS The proportion of eggs fertilized by cryopreser...

With the introduction of intracytoplasmic sperm injection (ICSI), couples with severe male factor infertility have achieved fertilization and clinical pregnancy rates comparable to other in-vitro fertilization (IVF) patients. However, failure of fertilization still occurs in some patients despite the utilization of microsurgical sperm injection techniques. How such fertilization failure after I...

Aims: Trypanosomiasis is an important protozoan disease that affects domestic and wild animals as well man. It caused by the tsetse fly-transmitted extracellular hemo-flagellates belong to genus, Trypanosoma. In East Southern Africa, Human African (HAT) Trypanosoma brucei rhodesiense while in West Central it T. b. gambiense. Animal trypanosomiasis on other hand brucei, vivax, congolense. sub-Sa...

The success of endodontic treatment not only lies in meticulous cleaning, perfect shaping and precise filling of canels, it also embodies vital importance on familiarity of unusual root canal patterns. This article presents a case report of a maxillary first molar that had two separate palatal roots with distinct canals and also an invitro assessment of an extracted tooth which had a a similar ...

The study was designed to evaluate the anti-inflammatory and antioxidant activity of a poly herbal formulation-Chyavana drink. The inflammation was induced in albino rats by carrageenan. The formulation was effective when compared with a known anti-inflammatory drug. The antioxidant activity was studied by invitro methods. The DPPH radical scavenging activity was found to be showing higher perc...
