Natsumi Endo, Reimi Kuroki, Tomomi Tanaka
The productive and reproductive characteristics of Brown Swiss (B) cross-bred cows were investigated by comparing with those of Holstein (H) cows housed in the same barn. Additionally, their hair cortisol levels were analyzed to evaluate the extent of stress experienced during dry and lactation periods. B cross-bred cows had lower milk yields and higher milk fat rates than H cows. Reproductive records showed that days from parturition to first artificial insemination (AI) in B cross-bred (n = 16) and H (n = 27) cows were not significantly different, but conception rate at first AI of B cross-bred cows tended to be higher than that of H cows...

Objective: Osteosarcoma (OS) is the most common malignant bone tumor in children and young adults. Many studies have shown that microRNAs play a critical role in proliferation and metastasis with this tumour type. However, whether aberrant expression might contribute to a metabolism switch in osteosarcoma cases is not clearly understood. In this study, we explored expression and function of miR-150 in osteosarcoma cells. Materials and methods: Expression of miR-150 was assessed by real-time PCR in cell lines and human patient tissues...

IGFs and IGF-binding proteins (IGFBPs) are abundantly present in milk and in dairy products. Compared to the IGFs, the IGFBP have received less attention in milk, although truncated IGFBPs and IGFBP-glycosylation have been described in milk. Thereby, complex control of local IGF-effects can be assumed on the levels of IGFBPs, proteases, and protease inhibitors. The present review collects the current knowledge both on presence and regulation of IGFs and IGFBPs in milk particularly from dairy animal species...

Bacterial formate-nitrite transporters (FNT) regulate the metabolic flow of small weak mono-acids derived from anaerobic mixed-acid fermentation, such as formate, and further transport nitrite, and hydrosulfide. The eukaryotic Plasmodium falciparum FNT is vital for the malaria parasite by its ability to release the larger l-lactate substrate as the metabolic end product of anaerobic glycolysis in symport with protons preventing cytosolic acidification. However, the molecular basis for substrate discrimination by FNTs has remained unclear...

Carbohydrate fuel augmentation following traumatic brain injury may be a viable treatment to improve recovery when cerebral oxidative metabolism of glucose is depressed. We performed a primed constant sodium L-lactate infusion in 11 moderate to severely brain injured adults. Blood was collected before and periodically during the infusion study. We quantified global cerebral uptake of glucose and lactate and other systemic metabolites associated with energy metabolism. Our hypothesis was that cerebral lactate uptake, as measured by the arteriovenous difference of lactate (AVDlac), would increase in severely injured TBI patients in the neurocritical care unit...

Early mortality (EM; death ≤ 6 months from diagnosis) has been reported in several newly diagnosed multiple myeloma (NDMM) trials. Before the era of novel agents, the incidence was 10%-14%. Causes of death included infections/pneumonia, renal failure, refractory disease, and cardiac events. Staging systems, such as the revised International Staging System (r-ISS), and prognostic factors including cytogenetics, lactate dehydrogenase levels, and myeloma-specific factors, are useful to assess overall prognosis; however, they cannot predict EM...

BACKGROUND: Kashmir has a population that largely consumes polished rice which is deficient in thiamine. Furthermore, lactating women in this region are prone to severe thiamine deficiency because of their traditional food avoidance practices. Infantile beriberi is common in exclusively breastfed infants of thiamine deficient mothers in Kashmir. METHODS: This was a one year prospective hospital-based study. We included 50 exclusively breastfed infants in our study...

Significant alterations in maternal calcium (Ca2+) and magnesium (Mg2+) balance occur during lactation. Ca2+ is the primary divalent cation mobilized into breast milk by demineralization of the skeleton and alterations in intestinal and renal Ca2+ transport. Mg2+ is also concentrated in breast milk, but the underlying mechanisms are not well understood. To determine the molecular alterations in Ca2+ and Mg2+ transport in the intestine and kidney during lactation, 3 groups of female mice consisting of either non-pregnant controls, lactating mice, or mice undergoing involution were examined...

The role of breastfeeding in improving allergy outcomes in early childhood is still unclear. Evidence suggests that immune mediators in human milk (HM) play a critical role in infant immune maturation as well as protection against atopy/allergy development. We investigated relationships between levels of immune mediators in colostrum and mature milk and infant outcomes in the first year of life. In a large prospective study of 398 pregnant/lactating women in the United Kingdom, Russia and Italy, colostrum and mature human milk (HM) samples were analysed for immune active molecules...

BACKGROUND: During traumatic hemorrhage, the ability to identify shock and intervene prior to decompensation is paramount to survival. Lactate is extremely sensitive to shock and its clearance has been demonstrated a useful gauge of shock and resuscitation status. Though lactate can be measured in the field, logistical constraints render it impractical in certain environments. The Compensatory Reserve represents a new clinical measurement reflecting the remaining capacity to compensate for hypoperfusion...

BACKGROUND: Despite improvements in the management of severely injured patients, development of multiple organ dysfunction syndrome (MODS) remains a morbid complication of traumatic shock. One of the key attributes of MODS is a profound bioenergetics crisis, for which the mediators and mechanisms are poorly understood. We hypothesized that metabolic uncoupling using an experimental PI3-kinase inhibitor, LY294002 (LY), may prevent mitochondrial abnormalities that lead to the generation of mitochondrial DNA (mtDNA) damage and the release of mtDNA damage associated molecular patterns (DAMPs) METHODS: 16 swine were studied using LY294002 (LY), a non-selective PI3-KI: Animals were assigned to Trauma only (TO, N=3); LY drug only (LYO, N=3); and Experimental (N=10), trauma + drug (LY+T) groups...
