#1
REVIEW
Bronwyn Anne Clayton
Nipah virus is a recently-recognised, zoonotic paramyxovirus that causes severe disease and high fatality rates in people. Outbreaks have occurred in Malaysia, Singapore, India and Bangladesh, and a putative Nipah virus was also recently associated with human disease in the Philippines. Worryingly, human-to-human transmission is common in Bangladesh, where outbreaks occur with near-annual frequency. Onward human transmission of Nipah virus in Bangladesh is associated with close contact with clinically-unwell patients or their infectious secretions...

Nano-ecotoxicology is an emerging science which aims to assess the environmental effect of nanotechnologies. The development of this particular aspect of ecotoxicology was made necessary in order to evaluate the potential impact of recently produced and used materials: nanoparticles (NPs). Among all the types of NPs, carbon nanoparticles (CNPs) especially draw attention giving the increasing number of applications and integration into consumer products. However the potential impacts of CNPs in the environment remain poorly known...

The proliferation of new psychoactive substances (NPS) has been a global trend in drug abuse and its regulation has been a worldwide concern. There is no doubt that it is necessary to share information related to these emerging substances between countries and continents for the effective regulation of NPS. With efforts for the efficient regulation of NPS, many studies and information have been published for the prevalence of NPS in the United States and other countries in Europe and Oceania. However, there is lack of information available for the prevalence of NPS in Asian and African countries...

Interneurons play a critical role in sculpting neuronal circuit activity and their dysfunction can result in neurological and neuropsychiatric disorders. To temporally structure and balance neuronal activity in the adult brain interneurons display a remarkable degree of subclass-specific plasticity, of which the underlying molecular mechanisms have recently begun to be elucidated. Grafting new interneurons to pre-existing neuronal networks allows for amelioration of circuit dysfunction in rodent models of neurological disease and can reopen critical windows for circuit plasticity...

Immune checkpoints, a plethora of inhibitory pathways aimed at maintaining immune cell homeostasis, may be co-opted by cancer cells to evade immune destruction. Therapies targeting immune checkpoints have reached a momentum yielding significant clinical benefits in patients with various malignancies by unleashing anti-tumor immunity. Galectins, a family of glycan-binding proteins, have emerged as novel regulatory checkpoints that promote immune evasive programs by inducing T-cell exhaustion, limiting T-cell survival, favoring expansion of regulatory T cells, de-activating natural killer cells and polarizing myeloid cells toward an immunosuppressive phenotype...

BACKGROUND AND OBJECTIVES: Emerging Adults (ages 18-25) have the highest prevalence of substance use disorders and rarely receive treatment from the specialty care system. Thus, it is important to have screening instruments specifically developed for emerging adults for use in Screening, Brief Intervention and Referral to Treatment (SBIRT) models. Optimal cutoffs for the widely-used GAIN Short-Screener's (GAIN-SS) Substance Disorder Screener (SDScrY) are not established specifically for emerging adults...

Plant biotechnology has been around since the advent of humankind, resulting in tremendous improvements in plant cultivation through crop domestication, breeding and selection. The emergence of transgenic approaches involving the introduction of defined DNA sequences into plants by humans has rapidly changed the surface of our planet by further expanding the gene pool used by plant breeders for plant improvement. Transgenic approaches in food plants have raised concerns on the merits, social implications, ecological risks and true benefits of plant biotechnology...

The artificial increase of the physical capability of horses using drugs is well-known in racing and in other equine sports. Both illicit and therapeutic substances are regarded as prohibited substances in competition in most countries. Some countries do make distinctions for a few, specific drugs which are, however, allowed for use in other countries. The primary objective in the case of doping control is the detection of any trace of drug exposure, either parent drug or any of its metabolites, using the most powerful analytical methods which generally are based on chromatographic/mass spectrometric techniques...

We describe a case of vitamin-D-deficiency rickets in a young child to highlight its existence in Malaysia where sunlight is abundant throughout the year. The child presented with deformity of both legs. He came from an educated urban family but remained indoors most of the time. Radiographs of knees and wrists showed changes of florid rickets. Low serum 25-hydoxyvitamin-D, high parathyroid hormone, normal serum phosphate and calcium levels, and normal renal function clinched the diagnosis of vitamin-D-deficiency rickets...

Immunity against Mycobacterium tuberculosis requires a balance between adaptive immune responses to constrain bacterial replication and the prevention of potentially damaging immune activation. Regulatory T (Treg) cells express the transcription factor Foxp3+ and constitute an essential counterbalance of inflammatory Th1 responses and are required to maintain immune homeostasis. The first reports describing the presence of Foxp3-expressing CD4+ Treg cells in tuberculosis (TB) emerged in 2006. Different Treg cell subsets, most likely specialized for different tissues and microenvironments, have been shown to expand in both human TB and animal models of TB...

Within the mammalian urinary tract uropathogenic bacteria face many challenges, including the shearing flow of urine, numerous antibacterial molecules, the bactericidal effects of phagocytes, and a scarcity of nutrients. These problems may be circumvented in part by the ability of uropathogenic Escherichia coli and several other uropathogens to invade the epithelial cells that line the urinary tract. By entering host cells, uropathogens can gain access to additional nutrients and protection from both host defenses and antibiotic treatments...

Urinary tract infection (UTI) pathogenesis is understood increasingly at the level of the uropathogens and the cellular and molecular mediators of host inflammatory responses. However, little is known about the mediators of symptoms during UTI and what distinguishes symptomatic events from asymptomatic bacteriuria. Here, we review bladder physiology and sensory pathways in the context of an emerging literature from murine models dissecting the host and pathogen factors mediating pain responses during UTI. The bladder urothelium is considered a mediator of sensory responses and appears to play a role in UTI pain responses...

An endoplasmic reticulum (ER)-resident protein that regulates cytosolic and ER free-Ca(2+) concentration by induction of store-operated calcium entry. That is the original definition of STIM2 and its function. While its activity strongly depends on the amount of calcium stored in the ER, its function goes further to intracellular signalling and gene expression. Initially undercovered by the prominent function of STIM1, STIM2 became to be vital in mice, gradually emerging as an important player in the nervous system, and cooperating with STIM1 in the immune system...

Traditional measures of overall glucose control, such as glycated hemoglobin (A1C), may not fully capture short-term, rapid changes in blood glucose. With the availability of multiple options to control A1C, glycemic fluctuations have emerged as an additional therapeutic goal for the management of type 2 diabetes (T2D).
