Calorie restriction (CR) refers to a reduction of calorie intake without compromising essential nutrients to avoid malnutrition. CR has been established as a non-genetic method of altering longevity and attenuating biological changes associated with aging. Aging is also an important risk factor for erectile dysfunction. The aim of this study was to examine whether CR diet can reverse the age-related alterations of erectile tissue in the aged rat. Four groups of rats were used: young rats (7 months) + ad libitum, aged rats (22 months) + ad libitum, young rats + CR diet, and aged rats + CR diet...

The GH3 family of adenylating enzymes conjugate acyl substrates such as the growth hormone indole-3-acetic acid (IAA) to amino acids via a two-step reaction of acyl substrate adenylation followed by amino acid conjugation. Arabidopsis thaliana GH3.5 was previously shown to be unusual in that it could adenylate both IAA and the defense hormone salicylic acid (SA, 2-hydroxybenzoate). Our detailed studies of the kinetics of GH3.5 on a variety of auxin and benzoate substrates provides insight into the acyl preference and reaction mechanism of GH3...

At the onset of puberty, ovarian hormones increase inhibitory tone in the prefrontal cortex. Inhibitory maturation is a hallmark of the initiation of developmental windows of neural plasticity; pubertal hormones may trigger the opening of an adolescent critical period for experience-dependent rewiring of circuits underlying executive function.

Plant adaptive responses to abiotic stress are coordinated by restriction of plant growth and development. The plant hormone abscisic acid (ABA) is the key regulator of the response to abiotic stress, and its sensitivity determines abiotic stress tolerance levels. We previously showed that the E3 ubiquitin ligase CaAIRF1 functions as a positive regulator of ABA and drought stress via modulation of transcription and stability of the type 2C protein phosphatase CaADIP1. Here, we report the identification and functional analysis of a novel type 2C phosphatase, CaAIPP1 (Capsicum annuum CaAIRF1 Interacting Protein Phosphatase 1)...

Endometriosis is a chronic disease with the potential to cause devastating clinical manifestations such as infertility and chronic pelvic disease. Current treatment is limited to surgical intervention and pharmacologic therapy targeting estrogen and progesterone to suppress ectopic endometrial tissue proliferation. Undesired side effects and contraindications to the use of hormonal medications may reduce treatment options. As the pathogenesis of endometriosis continues to be investigated, new therapies will emerge...

Monocarboxylate transporter 8 (MCT8) is an active and specific thyroid hormone transporter into neurons. MCT8 mutations cause an X-linked condition known as Allan-Herndon-Dudley syndrome and are characterized by impaired psychomotor development and typical abnormal thyroid function. We describe a 10-year-old boy with severe cognitive disability, axial hypotonia, spastic quadriplegia and sporadic dyskinetic episodes. He initially presented with thyroid dysfunction (high FT3, low rT3, low FT4 and normal TSH) and generalized retardation of the cerebral and cerebellar myelination in brain magnetic resonance imaging...

Parathyroid hormone receptors are present in bone cells and play a crucial role in the maintenance of skeletal integrity, bone homeostasis and regulation of calcium and phosphate metabolism. Although the function of these receptors has long being recognized in the cells of the osteoblastic lineage regulating directly osteoblast differentiation and function and indirectly osteoclastogenesis, recent findings demonstrate their functional presence in osteocytes participating in the co-ordination of bone remodelling...

Pituitary tumors represent 10-15% of all intracranial tumors; of these, prolactinomas account for 40-50% of cases. Prolactinomas usually respond well to dopamine agonists (DA) as first-line therapy. However, treatment resistance remains a concern. Temozolomide (TMZ) is an oral alkylating agent that has shown promise in treating aggressive pituitary adenomas and carcinomas that are resistant to other therapies. To date, no control trials have been undertaken and only single case reports of pituitary tumors treated with TMZ have been published...

BACKGROUND: Endometriosis is defined as the presence of endometrial tissue (glands and stroma) outside the uterine cavity. This condition is oestrogen-dependent and thus is seen primarily during the reproductive years. Owing to their antiproliferative effects in the endometrium, progesterone receptor modulators (PRMs) have been advocated for treatment of endometriosis. OBJECTIVES: To assess the effectiveness and safety of PRMs primarily in terms of pain relief as compared with other treatments or placebo or no treatment in women of reproductive age with endometriosis...

The mechanisms linking ovarian hormones to negative affect are poorly characterized, but important clues may come from the examination of the brain's intrinsic organization. Here, we studied the effects of both the menstrual cycle and oral contraceptives (OCs) on amygdala and salience network resting-state functional connectivity using a double-blind, randomized, and placebo-controlled design. Hormone levels, depressive symptoms, and resting-state functional connectivity were measured in 35 healthy women (24...

BACKGROUND: Regulation of calcium is mediated by parathyroid hormone (PTH) and 1.25-dihydroxyvitamine D3. The calcium-sensing receptor (CaSR) regulates PTH release by a negative feedback system. Gain-of-function mutations in the CaSR gene reset the calcium-PTH axis, leading to hypocalcaemia. PATIENTS AND METHODS: We analysed a family with hypocalcaemia. The proband was a 47-year-old man (index, patient I1), who presented with paraesthesias in both limbs. He has two sons (patient II1 a nd I I2)...
