Nowadays defying homology relationships among sequences is essential for biological research. Within homology the analysis of orthologs sequences is of great importance for computational biology, annotation of genomes and for phylogenetic inference. Since 2007, with the increase in the number of new sequences being deposited in large biological databases, researchers have begun to analyse computerized methodologies and tools aimed at selecting the most promising ones in the prediction of orthologous groups...

The purpose of this research has been deciphering the Warburg paradox, the biochemical enigma unsolved since 1923. This paradox consists of the aerobic pyruvate conversion to lactate brought about by anaplastic cancer, through the metabolic pathway known as aerobic glycolysis. This pathway implies a heavy energetic waste. We solved the enigma by demonstrating that its specific character, i.e. the forced aerobic lactate exportation, represents a crucial metabolic device to counteract the cytotoxic effect produced by an excess of pyruvate at the connection of glycolysis with the Krebs cycle...

Objective There is scant research examining the prevalence of thinness in early childhood, despite its potential negative consequences for health and development across the life course. The objective of this study was to assess bone status through measurement of bone mineral density and biochemical bone turnover markers, with special attention paid to carboxylated (c-OC) as well as undercarboxylated (uc-OC) forms of osteocalcin, in the groups of thin and normal-weight children. Design The study included 80 healthy prepubertal children (median age 7...

Organic matter derived from living, or recently living plant and animal, which can be used as fuel is called as biomass. It includes wood and agricultural waste such as dead plant etc. In India, majority of population depends largely upon agriculture as their primary source of income. Following every harvest, a huge amount of biomass is generated. It is mostly discarded as "agro waste"; however, recently, several uses of biomass and its derivatives have been reported. Thermochemical processing of biomass in absence of oxygen produces biomass char and flue gases which are of economic importance...

Childhood fracture may predict persistent skeletal fragility, but it may also reflect high physical activity which is beneficial to bone development. We observe a difference in the relationship between previous fracture and bone outcome across physical activity level and sex. Further elaboration on this variation is needed. PURPOSE: Childhood fracture may be an early marker of skeletal fragility, or increased levels of physical activity (PA), which are beneficial for bone mineral accrual...

OBJECTIVE: Most transgender women depend on medical treatment alone to lower testosterone levels in order to align physical appearance with gender identity. The medical regimen in the United States typically includes spironolactone and estrogens. The purpose of this cross-sectional study was to assess the testosterone suppression achieved among transgender women treated with spironolactone and estrogens. METHODS: Testosterone and estradiol levels were extracted from the electronic medical records of 98 anonymized transgender women treated with oral spironolactone and oral estrogen therapy at the Endocrinology Clinic at Boston Medical Center...

The current study was to evaluate the protective effects of Chinese medicine prescription Zuogui Pill (ZGP) on osteoporosis (OP) in zebrafish larvae induced by dexamethasone. Alizarin Red staining, calcium and phosphorus determination were performed to evaluate the effect of ZGP on bone mineralization. Hydroxyproline (HP), Alkaline phosphatase (ALP), and tartrate resistant acid phosphatase (TRAP) were also measured by commercial kits. We found that ZGP had positive effects in increasing bone mineral content (BMC), strengthening bone biomechanical, promoting bone formation, inhibiting bone resorption, and mediating protein levels of TGF-β1/Smads signaling pathway...

ᅟ: Bacterial microcompartments (BMC) are proteinaceous organelles that structurally resemble viral capsids, but encapsulate enzymes that perform various specialized biochemical reactions in the cell cytoplasm. The BMC are constructed from two major shell proteins, BMC-H and BMC-P, which form the facets and vertices of the icosahedral assembly, and are functionally equivalent to the major and minor capsid proteins of viruses, respectively. This equivalence notwithstanding, neither of the BMC proteins displays structural similarity to known capsid proteins, rendering the origins of the BMC enigmatic...

S Oliviero, Y Lu, M Viceconti, E Dall'Ara
Micro-Computed Tomography (microCT) images are used to measure morphometric and densitometric properties of bone, and to develop finite element (FE) models to estimate mechanical properties. However, there are concerns about the invasiveness of microCT imaging due to the X-rays ionising radiation induced by the repeated scans on the same animal. Therefore, the best compromise between radiation dose and image quality should be chosen for each preclinical application. In this study, we investigated the effect of integration time (time the bone is exposed to radiation at each rotation step during microCT imaging) on measurements performed on the mouse tibia...

EDITORIAL
Fabrizio Costa, Grant Cramer, E Jean Finnegan
The inclusive threshold policy for publication in BMC journals including BMC Plant Biology means that editorial decisions are largely based on the soundness of the research presented rather than the novelty or potential impact of the work. Here we discuss what is required to ensure that research meets the requirement of scientific soundness. BMC Plant Biology and the other BCM-series journals ( https://www.biomedcentral.com/p/the-bmc-series-journals ) differ in policy from many other journals as they aim to provide a home for all publishable research...

BACKGROUND: The chronic use of antipsychotics has been associated with impaired bone mineralization, partially mediated by hyperprolactinemia. We examined if calcium and vitamin D supplementation promote bone mineral accrual in boys with risperidone-induced hyperprolactinemia. METHODS: Between February 2009 and November 2013, medically healthy, 5- to 17-year-old boys were enrolled in a 36-week double-blind, placebo-controlled study, examining the skeletal effects of supplementation with 1250 mg calcium carbonate and 400 IU of vitamin D3 in risperidone-induced hyperprolactinemia...

The evaluation of key factors modulating cell homing following transplantation can provide new insights in the comprehension of unsolved biological questions about the use of cell therapies for osteoarthritis (OA). The main purpose of this in vivo study was to investigate the biodistribution of an intra-articular (IA) injection of mesenchymal stromal cells (MSCs) and bone marrow concentrate (BMC) in a rabbit OA model, and whether the additional use of sodium hyaluronate (HA) could modulate their migration and promote joint repair...

Diabetic neuropathy is one of the most common and serious complications of diabetes mellitus and metabolic syndrome. The current therapy strategies, including glucose control and pain management, are not effective for most patients. Growing evidence suggests that infiltration of inflammation factors and deficiency of local neurotrophic and angiogenic factors contribute significantly to the pathologies of diabetic neuropathy. Experimental and clinical studies have shown that bone marrow-derived stem cells (BMCs) therapy represents a novel and promising strategy for tissue repair through paracrine secretion of multiple cytokines, which has a potential to inhibit inflammation and promote angiogenesis and neurotrophy in diabetic neuropathy...

BACKGROUND: The free-living nematode Diploscapter coronatus is the closest known relative of Caenorhabditis elegans with parthenogenetic reproduction. It shows several developmental idiosyncracies, for example concerning the mode of reproduction, embryonic axis formation and early cleavage pattern (Lahl et al. in Int J Dev Biol 50:393-397, 2006). Our recent genome analysis (Hiraki et al. in BMC Genomics 18:478, 2017) provides a solid foundation to better understand the molecular basis of developmental idiosyncrasies in this species in an evolutionary context by comparison with selected other nematodes...

BACKGROUND: Spleen reserves monocytes, which deploy to inflammatory sites. Monocytosis is known to be observed in chronic low-grade inflammatory state, including chronic heart failure (CHF). CHF also induces splenomegaly. We tested the hypotheses that the number of peripheral blood monocytes and size of spleen at baseline could be related to the response to cardiac resynchronization therapy (CRT). METHODS: From 2010, a total of 49 consecutive patients implanted with CRT device were evaluated at baseline and 6-8 months later...

Trabecular bone score, an index of lumbar spine trabecular texture, has not been explored fully in adolescent girls. Our cross-sectional analysis supported the hypothesis that "adult normal" trabecular bone score has been achieved by the end of the first year post-menarche, providing a potential screening tool, independent from bone density. INTRODUCTION: Trabecular bone score (TBS) evaluates lumbar spine (LS) trabecular texture from DXA images. Limited evidence suggests low TBS in pre-pubertal girls...

BACKGROUND: Several cell-based therapies for adjunctive treatment of acute myocardial infarction have been investigated in multiple clinical trials, but the timing of transplantation remains controversial. We conducted a meta-analysis of randomized controlled trials to investigate the effects of timing on bone marrow-derived cell (BMC) therapy in acute myocardial infarction (AMI). METHODS: A systematic literature search of PubMed, MEDLINE, and Cochrane Evidence-Based Medicine databases from January 2000 to June 2017 was performed on randomized controlled trials with at least a 3-month follow-up for patients with AMI undergoing emergency percutaneous coronary intervention (PCI) and receiving intracoronary BMC transfer thereafter...
