Yoonjoo Choi, Deeptak Verma, Karl E Griswold, Chris Bailey-Kellogg
Therapeutic proteins are yielding ever more advanced and efficacious new drugs, but the biological origins of these highly effective therapeutics render them subject to immune surveillance within the patient's body. When recognized by the immune system as a foreign agent, protein drugs elicit a coordinated response that can manifest a range of clinical complications including rapid drug clearance, loss of functionality and efficacy, delayed infusion-like allergic reactions, more serious anaphylactic shock, and even induced auto-immunity...

It is an unprecedented time for the treatment of patients with chronic lymphocytic leukemia (CLL) with the recent approval of several targeted agents for use in frontline, relapsed, refractory, and high-risk disease. Traditionally, frontline management of CLL has been a combination of chemotherapy (fludarabine, cyclophosphamide, bendamustine, or chlorambucil) with an anti-CD20 monoclonal antibody (rituximab, ofatumumab, obinutuzumab). The current landscape is rapidly evolving with the advent of therapies that demonstrate selective inhibition of important pathways necessary for CLL proliferation and survival...

Chronic pulmonary hypertension (PH) is associated with right ventricular failure and high mortality regardless of the underlying disease. Currently, therapies can improve clinical outcomes in specific subsets of patients, but have little impact on the progression of pulmonary vascular remodeling. Upon new advances in vector development and delivery techniques, gene therapy is a novel strategy in this field with the potential of overcoming the main limitations of approved drug therapies: modulation of novel anti-remodeling targets and selective pulmonary vasculature targeting with minimal systemic effects...

Xian Kang, Dennis Hong, Mehran Anvari, Maria Tiboni, Nalin Amin, Scott Gmora
BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery is a safe and effective procedure for patients with severe obesity. One potential complication of LRYGB is the development of marginal ulcers (MUs). Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to significantly increase the likelihood of developing marginal ulcers after surgery. However, the risk associated with low-dose aspirin consumption is not well defined. We examined the impact of daily low-dose aspirin (81 mg) on the development of marginal ulcers following LRYGB...

Depression is a devastating disorder which has a high impact on the wellbeing of overall society. As such, need for innovative therapeutic agents are always there. Most of the researchers focused on N-methyl-d-aspartate receptor to explore the antidepressant like activity of new therapeutic agents. Dextromethorphan is a cough suppressant agent with potential antidepressant activity reported in mouse force swimming test. Considering N-methyl-d-aspartate as a forefront in exploring antidepressant agents, here we focused to unpin the antidepressant mechanism of dextromethorphan targeting N-methyl-d-aspartate receptor induced nitric oxide-cyclic guanosine monophosphate signaling...

Azole antifungals, known as demethylase inhibitors (DMIs), target sterol 14α-demethylase (CYP51) in the ergosterol biosynthetic pathway of fungal pathogens of both plants and humans. DMIs remain the treatment of choice in crop protection against a wide range of fungal phytopathogens that have the potential to reduce crop yields and threaten food security. We used a yeast membrane protein expression system to overexpress recombinant hexahistidine-tagged S. cerevisiae lanosterol 14α-demethylase and the Y140F or Y140H mutants of this enzyme as surrogates in order characterize interactions with DMIs...

South Africa has one of the highest burdens of TB worldwide, driven by the country's widespread prevalence of HIV, and further complicated by drug resistance. Active case finding within the community, particularly in rural areas where healthcare access is limited, can significantly improve diagnosis and treatment coverage in high-incidence settings. We evaluated the potential health and economic consequences of implementing community-based TB/HIV screening and linkage to care. Using a dynamic model of TB and HIV transmission over a time horizon of 10 years, we compared status quo TB/HIV control to community-based TB/HIV screening at frequencies of once every two years, one year, and six months...

Response to drug administration is a primary determinant for treatment success. Sex and gender disparities play a role in determining the efficacy and safety of the most common used medications suggesting the need for a sex-tailored approach in prescription. Statins are a cost-effective strategy for cardiovascular disease (CVD) prevention. While statins are similarly effective in secondary CVD prevention, some concerns raised by conflicting data reported in primary CVD prevention clinical trials. The small representation of women in clinical trials and the fewer rates of events due to the lower female baseline CVD risk may have conditioned contradictory meta-analysis findings...

OBJECTIVE In this study, the authors investigated the underlying mechanisms responsible for high tumor recurrence rates of adamantinomatous craniopharyngioma (ACP) after radiotherapy and developed new targeted treatment protocols to minimize recurrence. ACPs are characterized by the activation of the receptor tyrosine kinase epidermal growth factor receptor (EGFR), known to mediate radioresistance in various tumor entities. The impact of tyrosine kinase inhibitors (TKIs) gefitinib or CUDC-101 on radiation-induced cell death and associated regulation of survivin gene expression was evaluated...

The gag gene is highly polymorphic across HIV-1 subtypes and contributes to susceptibility to protease inhibitors (PI), a critical class of antiretrovirals that will be used in up to 2 million individuals as second-line therapy in sub Saharan Africa by 2020. Given subtype C represents around half of all HIV-1 infections globally, we examined PI susceptibility in subtype C viruses from treatment-naïve individuals. PI susceptibility was measured in a single round infection assay of full-length, replication competent MJ4/gag chimeric viruses, encoding the gag gene and 142 nucleotides of pro derived from viruses in 20 patients in the Zambia-Emory HIV Research Project acute infection cohort...

Substance use and abuse, which includes alcohol use, alcohol dependence, drug use, and drug dependence, inflicts a substantial toll on Americans. Although studies have demonstrated the protective effect of social support, such as religious participation and via marriage, understanding their influence on racial and ethnic minorities is limited. Thus, the aim of this study is to assess the impact of social support on substance use and abuse in racial and ethnic minorities. The Collaborative Psychiatric Epidemiology Surveys, sponsored by the National Institute of Mental Health, a repository of race, ethnicity, and mental health data, was leveraged to develop four models using multivariate analysis, specifically logistic regression to estimate the probability of meeting the criteria for substance use and abuse...

Cyclin-dependent kinase 2 (CDK2) has been reported to be essential for cell proliferation in several human tumours and it has been suggested as an appropriate target to be considered in order to enhance the efficacy of treatment regimens based on the use of DNA damaging drugs. We evaluated the clinical impact of CDK2 overexpression on a series of 21 high-grade osteosarcoma (OS) samples profiled by using cDNA microarrays. We also assessed the in vitro efficacy of the CDKs inhibitor roscovitine in a panel of drug-sensitive and drug-resistant human OS cell lines...

Myopia is not a simple refractive error, but an eyesight-threatening disease. There is a high prevalence of myopia, 80% to 90%, in young adults in East Asia; myopia has become the leading cause of blindness in this area. As the myopic population increases globally, the severity of its impact is predicted. Approximately one fifth of the myopic population has high myopia (≥-6 diopters), which results in irreversible vision loss such as retinal detachment, choroidal neovascularization, cataracts, glaucoma, and macular atrophy...

BACKGROUND: Intraperitoneal chemotherapy has an established role in the treatment of selected patients with colorectal peritoneal metastases. Oxaliplatin is highly suitable as a chemotherapeutic agent for hyperthermic intraperitoneal chemotherapy (HIPEC), but its use to date has been limited because of the morbidity caused by severe electrolyte and glycemic imbalances associated with 5% glucose as its carrier solution. This report provides an overview of the development, rationale, and application of intraperitoneal chemotherapy and the use of various drugs and carrier solutions...
