BACKGROUND: Bacterial genomes span a significant portion of diversity, reflecting their adaptation strategies; these strategies include nucleotide usage biases that affect chromosome configuration. Here, we explore an immuno-synergistic oligodeoxynucleotide (iSN-ODN, named iSN34), derived from Lactobacillus rhamnosus GG (LGG) genomic sequences, that exhibits a synergistic effect on immune response to CpG-induced immune activation. METHODS: The sequence of iSN34 was designed based on the genomic sequences of LGG...

Preventive and/or therapeutic interventions for ischemic heart disease have gained considerable attention worldwide. We investigated the mechanism(s) underlying cardioprotection of apocynin (APO) and whether it attenuates isoproterenol (ISO)-induced myocardial damage in vivo. Thirty-two male Wistar Albino rats were randomised into four groups (n = 8 for each group): Group I (Control); Group II (ISO), ISO was given intraperitoneally (ip) (150 mg/kg/d) daily for 2 consecutive days; Group III (APO + ISO), APO was applied ip 20 mg/kg 30 min before the first ISO administration and continued for the next 2 d after the second ISO administration; Group IV (ISO + APO), after the ISO treatment on days 1 and 2, 20 mg/kg APO was given ip on days 3 and 4...

Photosystem II (PS II) contains two redox-active tyrosine residues on the donor side at symmetrical positions to the primary donor, P680. TyrZ, part of the water-oxidizing complex, is a preferential fast electron donor while TyrD is a slow auxiliary donor to P680(+). We used PS II membranes from spinach which were depleted of the water oxidation complex (Mn-depleted PS II) to study electron donation from both tyrosines by time-resolved EPR spectroscopy under visible and far-red continuous light and laser flash illumination...

Sepsis is a life-threatening, overwhelming immune response to infection with high morbidity and mortality. Inflammatory response and blood clotting are caused by sepsis, which induces serious organ damage and death from shock. As a mechanism of pathogenesis, platelet-activating factor (PAF) induces excessive inflammatory responses and blood clotting. In this study, we demonstrate that a Class A CpG oligodeoxynucleotide (CpG-A1585) strongly induced PAF acetylhydrolase, which generates lyso-PAF. CpG-A1585 rescued mice from acute lethal shock and decreased fibrin deposition, a hallmark of PAF-induced disseminated intravascular coagulation...

An osteoblastic protein, osteocalcin (OC), exists in vivo in two forms: carboxylated OC, and uncarboxylated or low-carboxylated OC (ucOC). ucOC acts as a hormone to regulate carbon and energy metabolism. Recent studies demonstrated that ucOC exerts insulinotropic effects, mainly through the glucagon-like peptide 1 (GLP-1) pathway. GLP-1 is an insulinotropic hormone secreted by enteroendocrine L cells in the small intestine. Thus, efficient delivery of ucOC to the small intestine may be a new therapeutic option for metabolic diseases such as diabetes and obesity...

Cigarette package health warnings can be an important and low-cost means of communicating the health risks of smoking. We examined whether viewing health warnings in an experimental study influenced beliefs about the health effects of smoking, by conducting surveys with ~500 adult male smokers and ~500 male and female youth (age 16-18) in Beijing, China (n = 1070), Mumbai area, India (n = 1012), Dhaka, Bangladesh (n = 1018), and Republic of Korea (n = 1362). Each respondent was randomly assigned to view and rate pictorial health warnings for 2 of 15 different health effects, after which they reported beliefs about whether smoking caused 12 health effects...

The eukaryotic B-family DNA polymerases include four members: Polα, Polδ, Polϵ, and Polζ, which share common architectural features, such as the exonuclease/polymerase and C-terminal domains (CTDs) of catalytic subunits bound to indispensable B-subunits, which serve as scaffolds that mediate interactions with other components of the replication machinery. Crystal structures for the B-subunits of Polα and Polδ/Polζ have been reported: the former within the primosome and separately with CTD and the latter with the N-terminal domain of the C-subunit...

O'Brien et al (Research Article, 24 February 2017, eaag1789) proposed a novel mechanism of primase function based on redox activity of the iron-sulfur cluster buried inside the C-terminal domain of the large primase subunit (p58C). Serious problems in the experimental design and data interpretation raise concerns about the validity of the conclusions.

Safa Anwar, Nigar Shikalgar
Polycystic ovary syndrome (PCOS) is recognized as one of the most common endocrinopathies in women of reproductive age, associated with metabolic sequelae which includes increased risk factors for impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and cardiovascular disease (CVD). The adverse effects of DM2 affects a woman throughout her lifespan. Health care expenditure of DM2 highlights the need for prevention through appropriate screening, diagnosis and intervention. Lifestyle modification (LSM) programs that include diet and/or physical activity are suggested for patients characterized as prediabetic to delay the onset of adult DM2...

Humans have a bias for turning to the right in a number of settings. Here we document a bias in head-turning to the right in adult humans, as tested in the act of kissing. We investigated head-turning bias in both kiss initiators and kiss recipients for lip kissing, and took into consideration differences due to sex and handedness, in 48 Bangladeshi heterosexual married couples. We report a significant male bias in the initiation of kissing and a significant bias in head-turning to the right in both kiss initiators and kiss recipients, with a tendency among kiss recipients to match their partners' head-turning direction...

In this research article, a new mathematical model of delayed differential equations is developed which discusses the interaction among CD4 T cells, human immunodeficiency virus (HIV), and recombinant virus with cure rate. The model has two distributed intracellular delays. These delays denote the time needed for the infection of a cell. The dynamics of the model are completely described by the basic reproduction numbers represented by R0, R1, and R2. It is shown that if R0 < 1, then the infection-free equilibrium is locally as well as globally stable...

Lactoferrin (LF), an iron-binding glycoprotein distributed widely in the biological fluids of mammals, is believed to play an important role in host defenses against infection. Previous studies in animal models and humans demonstrated that combined administration of LF and probiotic lactic acid bacteria (LAB) can prevent sepsis. In this study, we genetically engineered a probiotic LAB strain, Lactococcus lactis, to produce recombinant bovine LF based on the green fluorescent protein (GFP)-fused expression system...

Oesophageal ulcers are a rare cause of upper Gastrointestinal Bleeding (GIB). In patients with Acquired Immune Deficiency Syndrome (AIDS), oesophageal diseases including oesophageal ulcers are very common. Idiopathic Oesophageal Ulcers (IOU) comprises a subgroup of oesophageal ulcers with no identifiable cause. IOU mainly present as odynophagia, retrosternal chest pain, decreased oral intake, and weight loss. Upper GIB is a rare presentation. In the era of Highly Active Anti Retroviral Therapy (HAART), with improvement in CD4 count, this entity is almost forgotten...

Fecal impaction if left untreated can lead to the hardening of stools and the formation of fecalith. Fecaliths rarely cause serious complications and are usually managed conservatively. We present this rare case of a giant fecalith causing near obstruction in an institutionalized paraplegic patient at high risk for chronic constipation and fecal impaction. This case was also unusual for causing ischemic pressure necrosis in the rectum, thereby highlighting the possible serious complications of fecalith.
