Weed control is a challenging event during crop cultivation. Integrated management, including the application of bioherbicides, is an emerging method for weed control in sustainable agriculture. Plant extracts, allelochemicals and some microbes are utilized as bioherbicides to control weed populations. Bioherbicides based on plants and microbes inhibit the germination and growth of weeds; however,few studies conducted in weed physiology. This review ascribes the current knowledge of the physiological changes in weeds that occur during the exposure to bioherbicides...

A growing body of evidence suggests that biological factors such as genes, hormone levels, brain structure, and brain functioning influence the development and trajectory of conduct problems in youth. In addition, biological factors affect how individuals respond to the environment, including how individuals respond to programs designed to prevent or treat conduct problems. Programs designed to reduce behavior problems in youth would have the greatest impact if they were targeted toward youth who need it the most (e...

During early pregnancy, the secretome of both oviduct and uterus serves as exchange medium for signaling factors between embryo and mother and provides the embryo with nutrients. The preimplantation embryo can utilize the fatty acids (FA) therein via direct incorporation into cell membrane lipid bilayers and for energy production via β-oxidation. The FA concentration and composition of the oviduct (OF) and uterine fluid (UF) might be regulated by ovarian hormones to meet the changing needs of the growing embryo...

For more than a decade, the sociology of hope and expectations has gained growing influence in the social studies of health, medicine, and healthcare. This literature has stressed the role of representations of the future-through images, metaphors, theories, or visions-in the medical sector and analyzed the translation of these discursive contents into social practices and organizations. This article builds on these results and intends to explore a dimension that has received less attention: the incarnation of medical promises...

The authors report a case of an orbital metastasis from an occult breast carcinoma. A 66-year-old woman presented with a growing left orbital tumour. Orbital CT scan was consistent with lymphoma. However, ocular pathology revealed small neoplastic cells showing an 'indian file pattern' suggestive of metastatic carcinoma and immunohistochemistry was positive for CK7, CK CAM5.2 and oestrogen receptor. A systemic evaluation was then performed with mammogram, breast ultrasound and MRI considered normal. An exhaustive systemic evaluation revealed multiple bone lesions, a right axillary lymph node lesion, which presented the same pattern on pathology and immunohistochemistry, with no evidence of a primary tumour...

The kidney vasculature facilitates the excretion of wastes, the dissemination of hormones, and the regulation of blood chemistry. To carry out these diverse functions, the vasculature is regionalized within the kidney and along the nephron. However, when and how endothelial regionalization occurs remains unknown. Here, we examine the developing kidney vasculature to assess its 3-dimensional structure and transcriptional heterogeneity. First, we observe that endothelial cells (ECs) grow coordinately with the kidney bud as early as E10...

A 58-year-old male patient was admitted at the São Bernardos's Hospital (Setúbal, Portugal) with generalised muscle spasms, dyspnoea, laryngospasm and bronchospasm in the context of severe hypocalcaemia. Despite efforts to correct serum calcium, it remained below average, leading to question the true cause of hypocalcaemia. Low parathyroid hormone and 25-hydroxyvitamin D, along with facial anomalies, palate defect and cognitive impairment with concomitant psychiatric disorder led to a suspicion of a DiGeorge/velocardiofacial/22q11...

Extra-axial cavernous hemangiomas (ECH) are rare vascular lesions with a tendency to grow within the medial structures of the middle cranial fossa. This pathological entity lacks specific symptoms, and falls into the category of differential diagnosis of space occupying lesions in the cavernous sinus (CS) with or without sellar involvement, including those of tumoral, vascular and inflammatory nature. Of note, ECH can also be indolent, and is at times discovered incidentally during autopsy investigations. On radiological studies, ECH with sellar extension are frequently mistaken at first for pituitary adenomas...

Plants, being sessile in nature, are constantly exposed to various environmental stresses, such as solar UV radiations, soil salinity, drought and desiccation, rehydration, low and high temperatures and other vast array of air and soil borne chemicals, industrial waste products, metals and metalloids. These agents, either directly or indirectly via the induction of oxidative stress and overproduction of reactive oxygen species (ROS), frequently perturb the chemical or physical structures of DNA and induce both cytotoxic or genotoxic stresses...

The aim was to verify the effect of follicle-stimulating hormone (FSH) supplementation to α-MEM+ or TCM199+ media on the in vitro development of ovarian preantral follicles (PFs) derived from collared peccaries. Ovaries (n = 5 pairs) were collected and divided into fragments destined to control group (non-cultured) or treatments that were cultured for 7 days. The PFs morphology, growth and activation were evaluated by classical histology. The immunohistochemistry markers Ag-NOR and PCNA were used for nuclear proliferation analysis, and the picrosirius red labelling was used for ovarian extracellular matrix (ECM) evaluation...

Suk-Young Lee, Jae Hong Seo
Currently, the growing population of the elderly is one of biggest problems in terms of increase in geriatric diseases. Lack of data from large prospective studies on geriatric breast cancer patients often makes it difficult for clinicians to make treatments decisions for them. Because both benefit and risk of treatment should be taken into account, treatment is usually determined considering life expectancy or comorbidities in elderly patients. Treatment of breast cancer is differentiated according to histologic classifications, and hormone therapy is even adopted for patients with metastatic breast cancer if tumor tissue expresses hormone receptors...

Context: Little is known about the health of transgender adults in the United States, a growing population. There have been no large reports examining differences in health status and cardiometabolic disease in subgroups of transgender adults [female-to-male (FTM), male-to-female (MTF), and gender nonconforming (GNC)] in the United States. Objective: Compare the health status and prevalence of cardiometabolic disease among specific subgroups of transgender adults (FTM, MTF, GNC) with those of cisgender adults in the United States...

Despite an estimated prevalence of 11% in women and plausible historical descriptions dating back to the 17th century, the etiology of endometriosis remains poorly understood. Classical theories of the histological origins of endometriosis are reviewed below. Clinical presentations are variable, and signs and symptoms do not correlate well with the extent of disease. In this summary, we have attempted to synthesize the growing evidence that hormonal and immune factors conspire to activate a local inflammatory microenvironment that encourages endometriosis to persist and elaborate mediators of its two cardinal symptoms: pain and infertility...

Steroid hormones are important mediators of prenatal maternal effects in animals. Despite a growing number of studies involving experimental manipulation of these hormones, little is known about the impact of methodological differences among experiments on the final results expressed as offspring traits. Using a meta-analytical approach and a representative sample of experimental studies performed on birds, we tested the effect of two types of direct hormonal manipulations: manipulation of females (either by implantation of hormone pellets or injection of hormonal solutions) and manipulation of eggs by injection...

Aneurysm formation is a complex multifactorial process with both genetic and environmental influences. Over recent years, there has been increasing recognition of sex-specific differences regarding the prevalence and natural history of cardiovascular diseases in the population. In particular, there is a growing body of evidence showing that aneurysm behaviour differs based on sex. Although most types of aneurysms are more common in men, their growth rates and outcomes are worse in women. This fact raises attention about potential underlying differences in the arteries of men and women that may contribute to differences in aneurysm prevalence and outcomes...

Seed plants are sessile organisms that have developed a plethora of strategies for sensing, avoiding, and responding to stress. Several proteins, including the glycine-rich protein (GRP) superfamily, are involved in cellular stress responses and signaling. GRPs are characterized by high glycine content and the presence of conserved segments including glycine-containing structural motifs composed of repetitive amino acid residues. The general structure of this superfamily facilitates division of GRPs into five main subclasses...

Since recent research indicates that other modalities are at a minimum non-inferior to the NICE-recommended hormonal agent prostaglandin E2 (PGE2 ), a retrospective cohort study was conducted on 1971 consecutively induced singleton pregnancies. Multinominal regression analysis showed that the odds ratio (OR) for vaginal delivery with balloon-mediated labour induction (84% vaginal deliveries; OR 1.6; 95% CI 0.7-3.5) is similar to the PGE2 agents propess (81%; OR 1.2; 95% CI 0.68-1.98) and prostin (79%; OR 0...

Depression during pregnancy and in the post-partum period is a growing health issue. Venlafaxine, a representative of serotonin and noradrenaline reuptake inhibitors, is used to treat a wide spectrum of mood disorders. However, the limited number of prenatal and perinatal studies raises the question about the long-term consequences of venlafaxine therapy. The aim of this study was to investigate the effect of venlafaxine exposure during pregnancy and lactation on anxiety-like and depression-like behaviors, as well as adrenocortical hormone concentrations in the adult rat offspring...

Parasponia represents five fast-growing tropical tree species in the Cannabaceae and is the only plant lineage besides legumes that can establish nitrogen-fixing nodules with rhizobium. Comparative analyses between legumes and Parasponia allows identification of conserved genetic networks controlling this symbiosis. However, such studies are hampered due to the absence of powerful reverse genetic tools for Parasponia . Here, we present a fast and efficient protocol for Agrobacterium tumefaciens -mediated transformation and CRISPR/Cas9 mutagenesis of Parasponia andersonii ...
