Pressure Swing Adsorption Based Air Filtration/Purification Systems for NBC Collective Protection

The respiratory protection against chemical warfare agents (CWA) has become a worldwide security concern in light of the many recent international threats utilising CWA. Till date the carbon filtration was adequate to protect the soldiers from the threats of CWA. With the advent of further advancements in the CWA a new threat is looming large that is known as the carbon breakers. pressure swing adsorption (PSA) is a well-established gas separation technique in air separation, gas drying, and hydrogen purification separation. Recently, PSA technology has been applied in the area of chem-bio defence by virtue of its unique advantages. This article reviews recent advances and developments in the field of PSA based purification, separation, and its use in defense sector. This emerging and advanced PSA technology can provide regenerative nuclear, biological and chemical (NBC) collective protection for ground vehicles, aircraft, ships and shelters. This PSA technology challenges threat scenario developed which includes nerve, blood and blister agents, as well as a “carbon breaker” agent, and proved that this technology will be a viable concept for future NBC collective protection systems. New technological breakthroughs and greater sophistication of PSA technologies will transform the collective protection based PSA technology in real field sense, addressing the escalating threat of CWA. We conclude this review with future prospects and challenges associated with PSA technology

The THREAT-ARREST Cyber-Security Training Platform

Cyber security is always a main concern for critical infrastructures and nation-wide safety and sustainability. Thus, advanced cyber ranges and security training is becoming imperative for the involved organizations. This paper presets a cyber security training platform, called THREAT-ARREST. The various platform modules can analyze an organization’s system, identify the most critical threats, and tailor a training program to its personnel needs. Then, different training programmes are created based on the trainee types (i.e. administrator, simple operator, etc.), providing several teaching procedures and accomplishing diverse learning goals. One of the main novelties of THREAT-ARREST is the modelling of these programmes along with the runtime monitoring, management, and evaluation operations. The platform is generic. Nevertheless, its applicability in a smart energy case study is detailed

A PROSPECTIVE STUDY ON RISK FACTORS OF IRON DEFICIENCY ANEMIA IN PREGNANT WOMEN AND THEIR MANAGEMENT

Objective: Iron deficiency anemia during pregnancy leads to preterm birth, low birth weight and increases the incidence of postpartum hemorrhage (PPH) and the reason for the incidence of PPH is higher in India compared with the rest of the world. In this study, our main goal was to find out the risk factors and complications of iron deficiency anemia and their management in pregnant women. Methods: It is a prospective study done at Obstetrics and Gynecology Department in Government District Headquarters Hospital, Tiruppur. All subjects were analyzed in full detail and hemoglobin estimation was also done to the patients. Results: Study found that 52% shows moderate anemia followed by 30% mild and 18% severe, respectively. Risk factors are found in 55% cases. Study found an association between risk factors and severity of anemia. Conclusion: Iron deficiency anemia continues to be the commonest etiology of anemia in pregnancy. The prevalence of iron deficiency in a pregnant woman is amongst the highest in the world. Untreated iron deficiency has significant adverse feto-maternal consequences. Iron supplementation and antenatal care are the basic requirements to prevent anemia

Therapeutic Challenge with a CDK 4/6 Inhibitor Induces an RB-Dependent SMAC-Mediated Apoptotic Response in Non-Small Cell Lung Cancer.

Purpose: The retinoblastoma tumor suppressor (RB), a key regulator of cell-cycle progression and proliferation, is functionally suppressed in up to 50% of non-small cell lung cancer (NSCLC). RB function is exquisitely controlled by a series of proteins, including the CyclinD-CDK4/6 complex. In this study, we interrogated the capacity of a CDK4/6 inhibitor, palbociclib, to activate RB function. Experimental Design and Results: We employed multiple isogenic RB-proficient and -deficient NSCLC lines to interrogate the cytostatic and cytotoxic capacity of CDK 4/6 inhibition in vitro and in vivo We demonstrate that while short-term exposure to palbociclib induces cellular senescence, prolonged exposure results in inhibition of tumor growth. Mechanistically, CDK 4/6 inhibition induces a proapoptotic transcriptional program through suppression of IAPs FOXM1 and Survivin, while simultaneously augmenting expression of SMAC and caspase-3 in an RB-dependent manner. Conclusions: This study uncovers a novel function of RB activation to induce cellular apoptosis through therapeutic administration of a palbociclib and provides a rationale for the clinical evaluation of CDK 4/6 inhibitors in the treatment of patients with NSCLC

Marker-Assisted Breeding as Next-Generation Strategy for Genetic Improvement of Productivity and Quality: Can It Be Realized in Cotton?

The dawdling development in genetic improvement of cotton with conventional breeding program is chiefly due to lack of complete knowledge on and precise manipulation of fiber productivity and quality. Naturally available cotton continues to be a resource for the upcoming breeding program, and contemporary technologies to exploit the available natural variation are outlined in this paper for further improvement of fiber. Particularly emphasis is given to application, obstacles, and perspectives of marker-assisted breeding since it appears to be more promising in manipulating novel genes that are available in the cotton germplasm. Deployment of system quantitative genetics in marker-assisted breeding program would be essential to realize its role in cotton. At the same time, role of genetic engineering and in vitro mutagenesis cannot be ruled out in genetic improvement of cotton

Characterization of a new molecule capable of inhibiting several steps of the amyloid cascade in Alzheimer's disease

Introduction: Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder in elderly people. Existent therapies are directed at alleviating some symptoms, but are not effective in altering the course of the disease. Methods: Based on our previous study that showed that an Fiji-interacting small peptide protected against the toxic effects of amyloid-beta peptide (A beta), we carried out an array of in silico, in vitro, and in vivo assays to identify a molecule having neuroprotective properties. Results: In silico studies showed that the molecule, referred to as M30 (2-Octahydroisoquinolin-2(1H)-ylethanamine), was able to interact with the A beta peptide. Additionally, in vitro assays showed that M30 blocked A beta aggregation, association to the plasma membrane, synaptotoxicity, intracellular calcium, and cellular toxicity, while in vivo experiments demonstrated that M30 induced a neuroprotective effect by decreasing the toxicity of A beta in the dentate gyrus of the hippocampus and improving the alteration in spatial memory in behavior assays. Discussion Therefore, we propose that this new small molecule could be a useful candidate for the additional development of a treatment against AD since it appears to block multiple steps in the amyloid cascade. Overall, since there are no drugs that effectively block the progression of AD, this approach represents an innovative strategy. Significance: Currently, there is no effective treatment for AD and the expectations to develop an effective therapy are low. Using in silico, in vitro, and in vivo experiments, we identified a new compound that is able to inhibit A beta-induced neurotoxicity, specifically aggregation, association to neurons, synaptic toxicity, calcium dyshomeostasis and memory impairment induced by A beta. Because A beta toxicity is central to AD progression, the inhibition mediated by this new molecule might be useful as a therapeutic tool

The CXCR4-LASP1-eIF4F Axis Promotes Translation of Oncogenic Proteins in Triple-Negative Breast Cancer Cells

Triple-negative breast cancer (TNBC) remains clinically challenging as effective targeted therapies are lacking. In addition, patient mortality mainly results from the metastasized lesions. CXCR4 has been identified to be one of the major chemokine receptors involved in breast cancer metastasis. Previously, our lab had identified LIM and SH3 Protein 1 (LASP1) to be a key mediator in CXCR4-driven invasion. To further investigate the role of LASP1 in this process, a proteomic screen was employed and identified a novel protein-protein interaction between LASP1 and components of eukaryotic initiation 4F complex (eIF4F). We hypothesized that activation of the CXCR4-LASP1-eIF4F axis may contribute to the preferential translation of oncogenic mRNAs leading to breast cancer progression and metastasis. To test this hypothesis, we first confirmed that the gene expression of CXCR4, LASP1, and eIF4A are upregulated in invasive breast cancer. Moreover, we demonstrate that LASP1 associated with eIF4A in a CXCL12-dependent manner via a proximity ligation assay. We then confirmed this finding, and the association of LASP1 with eIF4B via co-immunoprecipitation assays. Furthermore, we show that LASP1 can interact with eIF4A and eIF4B through a GST-pulldown approach. Activation of CXCR4 signaling increased the translation of oncoproteins downstream of eIF4A. Interestingly, genetic silencing of LASP1 interrupted the ability of eIF4A to translate oncogenic mRNAs into oncoproteins. This impaired ability of eIF4A was confirmed by a previously established 5′UTR luciferase reporter assay. Finally, lack of LASP1 sensitizes 231S cells to pharmacological inhibition of eIF4A by Rocaglamide A as evident through BIRC5 expression. Overall, our work identified the CXCR4-LASP1 axis to be a novel mediator in oncogenic protein translation. Thus, our axis of study represents a potential target for future TNBC therapies
