Atypical functioning of female genitalia explains monandry in a butterfly

2021

Monandrous species are rare in nature, especially in animals where males transfer nutrients to females in the ejaculate. The proximate mechanisms responsible for monandry are poorly studied. In butterflies and moths, the male transfers a nutritious spermatophore into the corpus bursae (CB) of the female. The CB is a multifunctional organ that digests the spermatophore and has partial control of the post-mating sexual receptivity of the female. The spermatophore distends the CB and the post-mating sexual receptivity of the female is inversely proportional to the degree of distension. The CB of many butterfly species has a muscular sheath whose contractions mechanically contribute to digest t…

Fresh Human Orthotopic Ovarian Cortex Transplantation: Long-term Results

2006

An increasing number of young women are being diagnosed with cancer, and most cancer treatments have irreversibly negative effects on reproduction. Ovarian stimulation and preservation of oocytes or embryos is far from an ideal solution, in part because hormonal treatment may adversely affect some cancers. Another possibility is cryopreservation of ovarian tissue for later autotransplantation, but the ischemic damage caused by the procedure can lead to follicle loss. Using the ovarian medulla for orthotopic ovarian cortex transplantation might limit the risk of ischemia because the ovarian artery would assure a good blood supply. In addition, the medulla may have a role in follicular develo…

Mullarian-inhibiting substance reflects ovarian findings in women with polycystic ovary syndrome better than does inhibin-B

2005

Objective: To investigate Müllerian-inhibiting substance (MIS) levels in women with polycystic ovary syndrome (PCOS), as well as relationships to ovarian morphology, levels of inhibin B, and other reproductive hormones. Design: Prospective clinical study. Setting: Academic endocrinology centers in Palermo, Italy and New York. Patient(s): Forty-six women with PCOS, recruited on the basis of the classic criteria of chronic anovulation and hyperandrogenism, and 25 age-matched ovulatory controls. Intervention(s): Fasting blood was obtained in all subjects in the early follicular phase (days 5–6) after spontaneous or induced menses (in PCOS), and transvaginal ultrasounds were performed. Main Out…

Two-site ELISA for quantification of the terminal C5b-9 complement complex in plasma

1993

Abstract A quantitative ELISA procedure using monoclonal and polyclonal antibodies against neoantigens of the terminal C5b-9 complement complex has been developed. The ELISA was demonstrated to be both sensitive and reproducible. The normal range for C5b-9 determinations, defined as 2.5–97.5% interval of the values obtained in 76 healthy blood donors, was 3.12–10.3 AU/ml. The presence of rheumatoid factor did not affect the determination of C5b-9 as demonstrated by immunoabsorption studies.

Lipid and Apoprotein Profile in Renal Transplant Recipients

1991

Lipid and apoprotein profiles of renal transplant recipients were compared with that of a group of uremic patients on hemodialytic treatment. Total cholesterol, HDL-cholesterol, apo AI and apo B were higher and triglycerides, apo CII, apo CIII and apo E lower in renal transplant patients. Type IIa and IIb were the prevalent phenotypes in renal transplant recipients.

The influence of smoke volatiles on sexual maturation and juvenile hormone biosynthesis in the black army cutworm, Actebia fennica (Lepidoptera: Noct…

2000

0965-1748 (Print) Journal Article Research Support, Non-U.S. Gov't; Outbreaks of the black army cutworm, Actebia fennica, are associated with recently burned sites, where larvae feed on early successional plants. In the present paper we show that smoke volatiles stimulate juvenile hormone biosynthesis in virgin females, resulting in a more rapid rate of oocyte maturation and a significant advance in the age of first calling (the release of the sex pheromone) compared to control females. The ecological implications of this physiological effect are discussed.

Matrix Metalloproteases in Arterial Hypertension and their Trend after Antihypertensive Treatment

2017

<b><i>Background/Aims</i></b><b><i>:</i></b> Arterial hypertension is characterized by vascular remodelling, atherosclerosis and cardiovascular complications. Matrix metalloproteases (MPPs) are endopeptidases produced by all the cells present in the vascular wall and are involved in the regulation of the extracellular matrix protein turnover. MMPs contribute to blood vessel formation, remodelling, angiogenesis; whereas an altered expression or activity of MMPs or their tissue inhibitors (TIMPs) results correlated with the development and progression of cardiovascular complications. <b><i>Methods:</i></b> We examined the…

JAK3/STAT5/6 Pathway Alterations Are Associated with Immune Deviation in CD8+ T Cells in Renal Cell Carcinoma Patients

2010

To investigate the molecular mechanisms underlying altered T cell response in renal cell carcinoma (RCC) patients, we compared autologous and allogeneic CD8(+) T cell responses against RCC line from RCC patients and their HLA-matched donors, using mixed lymphocyte/tumor cell cultures (MLTCs). In addition, we analyzed the expression of molecules associated with cell cycle regulation. Autologous MLTC responder CD8(+) T cells showed cytotoxic activity against RCC cell lines; however the analysis of the distribution of CD8(+) T-cell subsets revealed that allogenic counterparts mediate superior antitumor efficacy. In RCC patients, a decreased proliferative response to tumor, associated with defe…

Nesting habitat requirements and nestling diet in the Mediterranean populations of Crested Tits <I>Lophophanes cristatus</I>

2009

Most bird species show specific habitat requirements for breeding and feeding. We studied the pattern of habitat occupation, nestling diet and breeding performance of Crested Tits Lophophanes cristatus in a "typical" (conifer- ous) and an "atypical" (Holm Oak Quercus ilex) forest in eastern Spain during 2005-2007. We aimed to determine which microhabitat characteristics in the Holm Oak forest could account for the presence of Crested Tits, and checked whether the nestling diet in the Holm Oak forest resembled that obtained in the pine forest. Vegetation maps were produced using GIS from observations made in the field (tree species, tree and shrub cover). Nestling diet was recorded through v…
