Both historically and at present, vector control is the most generally effective means of controlling malaria transmission. Insecticides are the predominant method of vector control, but the sterile insect technique (SIT) is a complementary strategy with a successful track record in both agricultural and public health sectors. Strategies of genetic and radiation-induced sterilization of Anopheles have to date been limited by logistical and/or regulatory hurdles. A safe and effective mosquito chemosterilant would therefore be of major utility to future deployment of SIT for malaria control...

From late nineteen nineties, the higher number of suitable renal transplant candidates has forced the transplant community to re-explore the whole spectrum of deceased donors after brain death (DBD) as well as after cardiac death (DCD); in practice, donors of older age and donors with more chronic diseases or "medical complexities". This new kidney donor population - finally defined as extended criteria donors (ECD) - currently comprises on average 20 to 25%. In his seminal paper in 2003 on the introduction of ECD in the US, Metzger et al...

The seed beetle Callosobruchus maculatus is a significant agricultural pest and increasingly studied model of sexual conflict. Males possess genital spines that increase the transfer of seminal fluid proteins (SFPs) into the female body. As SFPs alter female behaviour and physiology, they are likely to modulate reproduction and sexual conflict in this species. Here, we identified SFPs using proteomics combined with a de novo transcriptome. A prior 2D-sodium dodecyl sulphate polyacrylamide gel electrophoresis analysis identified male accessory gland protein spots that were probably transferred to the female at mating...

Alzheimer's disease (AD), the most common neurodegenerative disease, has a complex and widespread pathology that is characterized by the accumulation of amyloid [Formula: see text]-peptide (A[Formula: see text]) in the brain and various cellular abnormalities, including increased oxidative damage, an amplified inflammatory response, and altered mitogen-activated protein kinase signaling. Based on the complex etiology of AD, traditional medicinal plants with multiple effective components are alternative treatments for patients with AD...

Radiation therapy (RT) as part of multidisciplinary oncologic care has been marked by profound advancements over the past decades. As part of multimodality therapy for esophageal cancer (EC), a prime goal of RT is to minimize not only treatment toxicities, but also postoperative complications and hospitalizations. Herein, discussion commences with the historical approaches to treating EC, including seminal trials supporting multimodality therapy. Subsequently, the impact of RT techniques, including three-dimensional conformal RT, intensity-modulated RT, and proton beam therapy, is examined through available data...

Inflammation has long been associated with the thyroid and with thyroid cancers, raising seminal questions about the role of the immune system in the pathogenesis of advanced thyroid cancers. With a growing understanding of dynamic tumour-immune cell interactions and the mechanisms by which tumour cells evade antitumour immunity, the field of cancer immunotherapy has been revolutionised. In this Review, we provide evidence to support the presence of an antitumour immune response in advanced thyroid cancers linked to cytotoxic T cells and NK cells...

Since Isaac's and Lindenmann's seminal experiments over 50 years ago demonstrating a soluble factor generated from heat killed virus-stimulated chicken embryos could inhibit live influenza virus replication, the term interferon has been synonymous with inhibition of virus replication. While the antiviral properties of type 1 interferon (IFN-I) are undeniable, recent studies have reported expanding and somewhat unexpected roles of IFN-I signaling during both acute and persistent viral infections. IFN-I signaling can promote morbidity and mortality through induction of aberrant inflammatory responses and recruitment of inflammatory innate immune cell populations during acute respiratory viral infections...

A bedridden 90-year-old man with fever and elevated prostate-specific antigen (PSA) (49 ng/mL) was referred for differentiation between infection and tumor. F-FDG PET/CT was negative for infection, but Ga-PSMA PET/CT showed multiple lesions in prostate gland with infiltration to bladder wall and seminal vesicle, consistent with locally advanced prostate cancer. The lesion with the highest Ga-PSMA uptake was strongly avid for Ga-DOTATOC, suggesting neuroendocrine tumor differentiation. After hormonal therapy, PSA normalized, but chromogranin-A increased (from 251 to 398 ng/mL), inferring progression of neuroendocrine tumor differentiation...

INTRODUCTION: The development of implantable technology for cardiac rhythm management remains one of the seminal achievements of the second half of the 20th century. The development of artificial pacemakers for the electrical control of the cardiac rhythm has greatly enhanced the physician's ability to treat cardiac dysrhythmias. An ageing population and the extension of indications will in all probability result in an increasing number of cardiac device implantations. OBJECTIVE OF STUDY: To study mortality and morbidity in patients with permanent pacemaker implantation at a tertiary care hospital in North India...

The ovulation-inducing effect of seminal plasma was first reported in Bactrian camels over 30 years ago, and the entity responsible was dubbed 'ovulation-inducing factor' (OIF). More recent studies, primarily in llamas and alpacas, characterized the biological and chemical properties of OIF and ultimately identified it as βNGF. This recent discovery has allowed a convergence of knowledge previously separated by discipline and by mechanism; that is, neurobiology and reproductive biology, and autocrine/paracrine vs endocrine...

Estradiol-17β (E2) plays critical roles in female maturation, sexual receptivity, ovulation, and fertility. In many mammals, contact with males can similarly affect these female parameters, while male excretions contain significant quantities of E2 We administered radiolabeled estradiol ([(3)H]E2) to male mice in doses representing a small fraction of their endogenous E2 These males were paired with sexually-receptive females, and radioactivity was traced into the females' systems. In Experiment 1, males were given [(3)H]E2 at 24 and 1 h prior to mating...

Since the seminal publications from the Framingham study in the mid-sixties,(1) the measurement of lipid levels, mainly of total cholesterol, total triglycerides, and LDL and HDL cholesterol, is routine clinical practice for cardiovascular disease (CVD) and lipid-lowering therapy. A more detailed assessment of the lipid composition, that is, the molecular species that constitute the lipid classes is not widely used, mainly due to the caveats of assessing the lipidome. The human lipidome is estimated to include thousands of molecular lipid species with functional diversity...

Total body potassium content and proper distribution of potassium across the cell membrane is of critical importance for normal cellular function. Potassium homeostasis is maintained by several different methods. In the kidney, total body potassium content is achieved by alterations in renal excretion of potassium in response to variations in intake. Insulin and beta-adrenergic tone play critical roles in maintaining the internal distribution of potassium under normal conditions. Despite homeostatic pathways designed to maintain potassium levels within the normal range, disorders of altered potassium homeostasis are common...

Renal denervation started out as a very promising approach to treat resistant hypertension with a very strong conceptual and basic science frame work from Gerald DiBona's lab and extending into the early non shame clinical studies demonstrating proof of concept in SYMPLICITY HTN-1 and 2. SYMPLICITY-HTN 3 a properly done, sham control trial failed to show a benefit on further reduction of BP compared to the sham group. The conclusion the procedure doesn't work. How could this be-it was clearly effective in animal models but why not in man...
