Lead (Pb) contamination in soil represents a threat to human health. Phytoextraction has gained attention as a potential alternative to traditional remediation methods because of lower cost and minimal soil disruption. The North American native switchgrass (Panicum virgatum L.) was targeted due to its ability to produce high biomass and grow across a variety of ecozones. In this study switchgrass was chemically enhanced with applications of the soil-fungicide benomyl, chelates (EDTA and citric acid), and PGR to optimize phytoextraction of Pb and zinc (Zn) from contaminated urban soils in Atlanta, GA...

INTRODUCTION: Anti-Mullerian Hormone (AMH) is a useful endocrine marker for assessing the ovarian reserve. AMH serum level reflects the number of follicles that have made the transition from the primordial pool into the growing follicle pool, and it is not controlled by gonadotropins. AIM: The present study was conducted to correlate serum AMH levels with Polycystic Ovarian Syndrome (PCOS) and type of treatment protocol. MATERIALS AND METHODS: Serum AMH levels were performed in the early follicular phase (on 2(nd) day of menstrual cycle) both in infertile females including PCOS and control women...

Growth is one of the most crucial economic traits of all aquaculture species, but the molecular mechanisms involved in growth of largemouth bass (Micropterus salmoides) are poorly understood. The objective of this study was to screen growth-related genes of M. salmoides by RNA sequencing and identify growth-related single-nucleotide polymorphism (SNP) markers through a growth association study. The muscle transcriptomes of fast- and slow-growing largemouth bass were obtained using the RNA-Seq technique. A total of 54,058,178 and 54,742,444 qualified Illumina read pairs were obtained for the fast-growing and slow-growing groups, respectively, giving rise to 4,865,236,020 and 4,926,819,960 total clean bases, respectively...

Transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) are extensively cultivated worldwide. To counter rapidly increasing pest resistance to crops that produce single Bt toxins, transgenic plant "pyramids" producing two or more Bt toxins that kill the same pest have been widely adopted. However, cross-resistance and antagonism between Bt toxins limits the sustainability of this approach. Here we describe development and testing of the first pyramids of cotton combining protection from a Bt toxin and RNA interference (RNAi)...

Single-agent endocrine therapy has been the standard therapeutic choice for the management of hormone receptor (HR)-positive, Her2-negative advanced breast cancer (ABC) for decades. However, the rapidly accumulating data regarding the biological role and safety of CDK4/6 inhibitors and the first-in-class approval of palbociclib have made these novel agents an essential component of treatment for HR-positive ABC. In the frontline setting, palbociclib in combination with endocrine therapy showed an improvement in progression-free survival (PFS) by 10 months to nearly 25 months when compared with endocrine therapy alone and a clinical benefit rate (CBR = stable disease >24 weeks + partial response + complete response) of 85%...

Liver metastases from breast cancer (LMBC) have long been considered as a systemic disease because of the hematological route of dissemination, requiring noncurative management. In fact, despite recent advances in drug therapies personalized to tumor phenotype, the chances of a cure are nil and there is little hope of long-term survivors after nonsurgical management alone. By contrast, there is a growing evidence in the literature for satisfactory long-term results after a combination of chemotherapy and liver resection, with 5-year survival reaching >40% in some series...

Cardiovascular disease is a common co-morbidity and leading cause of death in patients with type 2 diabetes mellitus (T2DM). Glucagon-like peptide 1 (GLP-1) is a peptide hormone produced by intestinal L cells in response to feeding. Native GLP-1 (7-36) amide is rapidly degraded by diaminopeptidyl peptidase-4 (DPP4) to GLP-1 (9-36) amide, making 9-36a the major circulating form. While it is 7-36a, and not its metabolites, which exerts trophic effects on islet β-cells, recent studies suggest that both 7-36a and its metabolites have direct cardiovascular effects, including preserving cardiomyocyte viability, ameliorating cardiac function, and vasodilation...

A growing number of researchers are focusing their attention on the possibility that thyroid hormone metabolites, particularly 3,5-diiodothyronine (T2), may actively regulate energy metabolism at the cellular, rather than the nuclear, level. Due to their biochemical features, mitochondria have been the focus of research on the thermogenic effects of thyroid hormones. Indeed, mitochondrial activities have been shown to be regulated both directly and indirectly by T2-specific pathways. Herein, we describe the effects of T2 on energy metabolism...

The aim of this study was to assess the effects of increasing levels of expeller extracted canola meal (EECM) in diets for growing pigs on performance, gastrointestinal tract weight, thyroid gland weights, blood plasma concentration of triiodothyronine and tetraiodothyronine, red blood cell count, hemoglobin content in blood, and hematocrit. Four diets were fed to 48 pigs (19.9 ± 1.60 kg initial BW) in 24 pens (6 pens per diet) for 4 wk in a completely randomized design. The diets were a control corn-soybean meal basal diet and 3 additional diets produced by replacing 33, 66, or 100% of soybean meal with EECM to achieve inclusion levels of 0, 10, 20, and 30%...

As adverse health effects of bisphenol A (BPA) become a growing public health concern, the chemicals substituting BPA have been increasingly used in everyday lives. BPA substitutes have been frequently detected in both environment and biota in increasing levels. However, very limited toxicological information is available for these chemicals. In the present study, thyroid disrupting effects of nine structural analogues of BPA were evaluated along with BPA, using rat pituitary (GH3) and thyroid follicular (FRTL-5) cells...

Dominance or cooperation between ovarian follicles can determine the number of ovulations and fecundity, but interrelationships between follicles in mono- and poly-ovulatory species and their mechanisms are poorly understood. The goals of this work were to determine the existence and compare the character of mutual influence of cultured ovarian follicles from a mono-ovulatory species (cow) with established follicular dominance with those from a poly-ovulatory species (pig), in which interrelationship between follicles remain unknown, and to examine the role of ovarian cell proliferation, the insulin-like growth factor I (IGF-I)- oxytocin (OT) system, and steroid hormones in mediating interrelationships among ovarian follicles...

Gerbillus tarabuli is a nocturnal Saharan rodent which has an annual reproductive cycle characterized by the reproductive activity in spring and a long phase of sexual quiescence in other seasons. We describe the morphology and hormonal regulation of the prostatic complex of this rodent in the two periods, based on anatomical, histological, morphometric, and immunohistochemical analyses. The organisation of this prostatic complex is similar to that reported for Meriones unguiculatus, but different from the prostate of Psammomys obesus, the rat, and the mouse...

There is a growing need to increase productivity in poultry. Growth hormones and antibiotics have the ability to improve health, weight gain and feed efficiency in meat-producing animals. The growth-promoting antibiotics are administered to poultry to improve the general performance of the chicken. However, the use of the xenobiotic drugs in food-producing animals has been a concern and a sensitive issue of debate for several decades in the EU and many other regional blocks of the world. Consequently, the use of hormones in animal production has been banned in Italy, Denmark and Germany for over 4-5 decades, while Belgium and Greece had never permitted its use for livestock fattening purposes...

BACKGROUND: Only 10% of plasma TFPIα (TFPI) exists in the full length form, the rest circulates as a C-terminally truncated form. However, blood platelets exclusively contain full length TFPI, which is released at the site of injury upon platelet activation, and which could play an important local regulatory role in thrombin generation and prevention of thrombosis. METHODS: The anticoagulant activities of full length and truncated TFPI were investigated using thrombin generation assays...

Liquid chromatography mass spectrometry (LC-MS) is a widely used technique in the clinical laboratory, especially for small molecule quantitation in biological specimens, for example, steroid hormones and therapeutic drugs. Analysis of circulating macromolecules, including proteins and peptides, is largely dominated by traditional enzymatic, spectrophotometric, or immunological assays in clinical laboratories. However, these methodologies are known to be subjected to interfering substances, for example heterophilic antibodies, as well as subjected to non-specificity issues...

Juvenile hormone (JH) plays a crucial role in the determination of developmental timing in insects. In Drosophila melanogaster, reports indicate that JH titers are the highest immediately following eclosion and that the mating experience increases the titers in females. However, the titers have not been successively measured for an extended period of time after eclosion. This study reveals that JH titers are increased after eclosion in virgin females when supplied with food that is occupied by eggs and larvae as well as in mated females...

Laccases are encoded by a multigene family and widely distributed in plant genomes where they play roles oxidizing monolignols to produce higher-order lignin involved in plant development and stress responses. We identified 30 laccase genes (OsLACs) from rice, which can be divided into five subfamilies, mostly expressed during early development of the endosperm, growing roots, and stems. OsLACs can be induced by hormones, salt, drought, and heavy metals stresses. The expression level of OsLAC10 increased 1200-fold after treatment with 20 μM Cu for 12 h...

The ovarian reserve represents the stock of quiescent primordial follicles in the ovary which is gradually depleted during a woman's reproductive lifespan, resulting in menopause. Müllerian inhibiting substance (MIS) (or anti-Müllerian hormone/AMH), which is produced by granulosa cells of growing follicles, has been proposed as a negative regulator of primordial follicle activation. Here we show that long-term parenteral administration of superphysiological doses of MIS, using either an adeno-associated virus serotype 9 (AAV9) gene therapy vector or recombinant protein, resulted in a complete arrest of folliculogenesis in mice...

The case of a 78-year-old man with hormone-independent locally advanced prostatic cancer with liver metastases is reported. Standard systemic chemotherapy was not administered due to his poor general condition. At the initial consultation, rapidly growing liver metastases, multiple lymph node metastases, and extensive locally advanced prostatic lesions were found. Transcatheter arterial chemoembolization, low dose systemic chemotherapy, and thermotherapy were administered. After introduction of this combination therapy, marked regression of all of the lesions, including the liver metastases, lymph node metastases, and pelvic extension was observed...
