BACKGROUND/OBJECTIVE: Pregnant women experience a myriad of physiological and metabolic changes that affect different organ systems in the body. Cutaneous and appendageal alterations that manifest during pregnancy are largely modulated by hormonal, immunologic, and metabolic factors. Detailed reports encompassing physiological changes and specific dermatoses of pregnancy and effects of various dermatoses on pregnant women are scanty in literature. This study was conducted to examine in detail both physiological changes and specific dermatoses...

The ant genus Lenomyrmex was recently discovered and described from mid to high elevation rainforests in southern Central and northwestern South America. Lenomyrmex currently consists of six described species, which are only rarely collected. Here, we add a new species, Lenomyrmex hoelldoblerisp. n., which was discovered in a stomach content sample of the dendrobatid frog, Oophaga sylvatica, from northwestern Ecuador. Lenomyrmex hoelldobleri can be distinguished from other species in the genus by the presence of a well-developed petiolar node, whereas in all other species the node of the petiole is ill-defined...

In an electronic triode, the electron current emanating from the cathode is regulated by the electric potential on a grid between the cathode and the anode. Here we demonstrate a triode for single quantum magnetic field carriers, where the flow of individual magnetic vortices in a superconducting film is regulated by the magnetic potential of striae of soft magnetic strips deposited on the film surface. By rotating an applied in-plane field, the magnetic strip potential can be varied due to changes in the magnetic charges at the strip edges, allowing accelerated or retarded motion of magnetic vortices inside the superconductor...

In cytoplasmic inheritance, structural states of a parent cell could be transmitted to offspring cells via two mechanisms. The first is referred to as the hangover of parent structure, where the structure itself remains and faithfully transmits within offspring cells; the second is structural inheritance, wherein the parent structure functions as a template for development of new offspring structure. We estimated to what extent the parent structure affects the development of offspring structure by structural inheritance, using a clone of the diatom Cyclotella meneghiniana The cell has two siliceous valves (a cell wall part at both cell poles): one is inherited from the parent and the other is newly formed...

BACKGROUND: Striae are a common change during pregnancy, leaving striae in various body parts after delivery, which most women find unpleasant. They create a big aesthetic concern for most women. Although striae do not endanger the mother and the fetus, they may cause a desire to scratch the region leading to small wounds, induce stress over beauty, decrease self-confidence, and create psychological disorders. They may try various treatments and often refer to dermatology clinics and receive long-term treatments; these time-consuming and costly behaviors and may affect their quality of life...

Striae are common dermal lesions of unknown etiology. These stretch marks are linear and atrophic plaques due to the continuous and progressive distension of the skin (1,2,3). Their pathogenesis involves reductions and modifications in the configuration of the elastic fibers, collagen, and fibrillin of the dermis (3, 4), structures which are produced by fibroblasts. Striae and dystopic urogenital tissues have inactive fibroblasts causing deficiency in the contractility of the two conditions (4). This article is protected by copyright...

John Slapcinsky, Fred Kraus
We describe a new stylommatophoran land snail of the family Partulidae from Palau. The new species has a combination of morphological and ecological characters that do not allow its placement in any existing partulid genus, so we describe a new genus for it. The new genus is characterized by a large (18-23 mm) obese-pupoid shell; smooth protoconch; teleoconch with weak and inconsistent, progressively stronger, striae; last half of body whorl not extending beyond the penultimate whorl; widely expanded and reflexed peristome; relatively long penis, with longitudinal pilasters that fuse apically into a fleshy ridge that divides the main chamber from a small apical chamber; and vas deferens entering and penial-retractor muscle attaching at the apex of the penis...

PURPOSE: Striae distensae represent the result of the failure of the dermis to sustain intrinsic mechanical forces. Intensive moisturization of the lesions and use of emollient oils have been recommended for the prevention and treatment of striae distensae rubra. The aim of this research was to formulate an emollient water-in-oil cosmetic cream containing argan oil, which may be helpful in the prevention or early treatment of striae distensae. PATIENTS AND METHODS: Sensory evaluation of the consistency, firmness, adhesiveness, oiliness, spreadability, and rapidity of penetration into the skin was evaluated by 22 volunteers using 10-point scales for each descriptor...

: Transplantation of cryopreserved ovarian tissue has been shown to successfully induce pregnancies. Furthermore, puberty may be induced by transplanted ovarian tissue in girls suffering from premature primary ovarian insufficiency (PPOI) due to gonadotoxic therapy. Therefore, the question arises if ovarian tissue cryopreservation should be recommended for puberty induction in prepubertal girls with cancer prior to gonadotoxic therapies. Although this strategy seems to be more natural than administering exogenous steroid sex hormones, there are some disadvantages from the endocrinological point of view...

Flash-lamp pulsed-dye laser (FPDL) is a nonablative technology, typically used in vascular malformation therapy due to its specificity for hemoglobin. FPDL treatments were performed in a large group of patients with persistent and/or recalcitrant different dermatological lesions with cutaneous microvessel involvement. In particular, 149 patients (73 males and 76 females) were treated. They were affected by the following dermatological disorders: angiokeratoma circumscriptum, genital and extragenital viral warts, striae rubrae, basal cell carcinoma, Kaposi's sarcoma, angiolymphoid hyperplasia, and Jessner-Kanof disease...

OBJECTIVE: Striae gravidarum is a form of scarring on the skin observed during pregnancy and can cause serious cosmetic problems. Striae gravidarum may be influenced by hormonal changes, although the etiology is not clear. The aim of this study was to investigate whether body mass index (BMI) and serum collagenase-2 levels in pregnant women are related to the development of striae gravidarum. METHODS: Thirty pregnant women with striae, 30 pregnant women without striae, and 32 health controls were enrolled in the study...

Striae distensae are common undesirable skin lesions of significant aesthetic concern. To compare the efficacy of two fluences (75 and 100 J/cm(2)) of long-pulsed Nd:YAG laser in the treatment of striae. Forty-five patients (Fitzpatrick skin types III-V) aged between 11 and 36 years with striae (23 patients with rubra type and 22 with alba type) were enrolled in the study. Each stria was divided into three equal sections, whereby the outer sections were treated with long-pulsed 1064 nm Nd:YAG laser, at a fluence of 75 or 100 J/cm(2), and fixed laser settings of 5 mm spot size and 15 ms pulse duration...

Fractional radiofrequency (FRF) is renowned for its use in cosmetic dermatology, with regard to the treatment of rhytides, striae, scarring and cellulite. We have systemically analysed its evidence for the use of FRF in acne scars. Our search identified 15 articles, one single-blinded randomised controlled trial, two split-face trials and thirteen prospective clinical studies, mostly single-centred. Case reports were excluded. In total 362 patients were treated. The longest follow-up was for 210 days, and on average the follow-up was for three months, varying between one and seven months...

PURPOSE: To search for gold-standard histology indicators using alternative imaging modalities in keratoconic corneas. METHODS: Prospective observational case-control study. Fourteen keratoconic corneas and 20 normal corneas (10 in vivo healthy subjects and 10 ex vivo donor corneas) were examined. Images of corneas were taken by spectral domain optical coherence tomography (SD-OCT) and in vivo confocal microscopy (IVCM) before keratoplasty. The same removed corneal buttons were imaged after keratoplasty with full-field optical coherence microscopy (FFOCM) and then fixed and sent for histology...
