TL;DR: The functional importance of this complex ion channel in sperm motility and male fertility is highlighted and restricted localization and expression of CatSper in sperm offer an added advantage to developing gamete-based safe non-hormonal contraceptives.
Abstract: A number of physiological events, such as sperm hyperactivation, chemotaxis towards the egg, capacitation and acrosome reaction, are triggered by activation of sperm ion channels in response to a diverse range of chemical cues. Cation channel of sperm (CatSper), a sperm-specific ion channel, is unique in orchestrating the events for fertilization, and seems to be exclusively evolved for sperm function and male fertility. CatSper acts as a polymodal, chemosensory calcium channel and plays a vital role in the regulation of sperm hyperactivation. CatSper knockout models and application of patch clamp recordings have shown that it is indispensable for male fertility, and mutations and deletions in CatSper gene(s) may lead to infertility. In fact, mutations in CatSper1 and 2 have been identified in infertile individuals; however, CatSper3 and 4 have not been explored. Restricted localization and expression of CatSper in sperm offer an added advantage to developing gamete-based safe non-hormonal contraceptives. This review concisely covers identification, structure, function, and mechanism of action of CatSper channels. The functional importance of this complex ion channel in sperm motility and male fertility is highlighted for further research on male fertility, infertility, and contraception.

TL;DR: Oral administration of Picroliv resulted in a significant increase in haemagglutinating antibody (HA) titre, plaque forming cells (PFC), and delayed hypersensitivity (DTH) response to SRBC, and induced a high degree of protection in golden hamsters against challenge infection with Leishmania donovani promastigotes.
Abstract: Picroliv, a standardised fraction from root and rhizome of PICRORHIZA KURROA, consisting of iridoid glycosides and shown to be responsible for its hepatoprotective activity, was studied for immunostimulant activity. Oral administration of Picroliv (10 mg/kg x 7 days) in mice prior to immunization with sheep red blood cells (SRBC) resulted in a significant increase in haemagglutinating antibody (HA) titre, plaque forming cells (PFC), and delayed hypersensitivity (DTH) response to SRBC. Picroliv enhanced the non-specific immune response characterized by an increase in macrophage migration index (MMI), [ (14)C]-glucosamine uptake, phagocytosis of [ (14)C]-leucine labelled ESCHERICHIA COLI, chemiluminescence of peritoneal macrophages, and higher uptake of [ (3)H]-thymidine in the lymphocytes of treated mice. It also induced a high degree of protection in golden hamsters against challenge infection with LEISHMANIA DONOVANI promastigotes.

TL;DR: In vivo proton magnetic resonance spectroscopy was performed for 24 patients with pyogenic brain abscesses to examine the consistency of the spectral patterns and to observe the changes in metabolites with treatment, and it was concluded that spectral patterns for brainAbscesses are consistent and specific and can assist in the noninvasive diagnosis of abscesss.
Abstract: OBJECTIVE: In vivo proton magnetic resonance spectroscopy was performed for 24 patients with pyogenic brain abscesses, to examine the consistency of the spectral patterns and to observe the changes in metabolites with treatment. METHODS: Localized proton spectra were obtained from 4- to 8-ml volumes in the abscesses, using stimulated echo acquisition mode and spin echo sequences. Twenty-two patients were treated with combined surgical and medical therapy, and two patients were treated conservatively. High-resolution magnetic resonance spectroscopy was performed for 15 samples of abscesses obtained from these patients, to confirm the assignments of resonances seen in vivo. Postaspiration studies were performed for 12 patients treated with combined medical and surgical therapy and 2 patients treated medically. RESULTS: Lactate and amino acids were seen in spectra for all patients, irrespective of the time of spectroscopy after the onset of combined medical and surgical therapy. Acetate and pyruvate disappeared after 1 week of combined treatment. CONCLUSION: It was concluded that spectral patterns for brain abscesses are consistent and specific and can assist in the noninvasive diagnosis of abscesses. Responses to combined treatment could be monitored by showing the changes in metabolite patterns in serial spectroscopic studies.
