Human's application of safflower (Carthamus tinctorius) has a long history, but the origin remains unclear. Safflower was introduced into China for traditional Chinese medicine, and Sichuan was major producing area. However, in recent years, the main producing area is in Xinjiang province, in contrast Sichuan safflower is difficult to find. By reading relevant document literature and the production and marketing information of safflower, and having field investigation in the main producing areas, the origin of safflower and the reasons of producing areas' changes were explored...

INTRODUCTION: Heterologous breast reconstruction after mastectomy sometimes requires the management of the contralateral breast to achieve symmetric long lasting aesthetic results. Some techniques could be used for the symmetrization of contralateral breast with or without implants as breast augmentation, reduction mammoplasty, mastopexy, with T inverted, J, vertical, periareolar, semi-circular, or axillary scars. The aim of this study is to present the use of crescent mastopexy technique with implants in contralateral adjustment following monolateral breast reconstruction compared with a control group in which patients underwent other contralateral procedures...

BACKGROUND: HSV-1 epidemiology in the Middle East and North Africa (MENA) remains poorly understood. Our study aimed to measure HSV-1 antibody prevalence (seroprevalence) and its age-distribution among select MENA populations residing in Qatar. METHODS: Sera were collected from male blood donors attending Hamad Medical Corporation 2013-2015. A total of 2,077 sera were tested for anti-HSV-1 antibodies using HerpeSelect® 1 ELISA IgG kits (Focus Diagnostics, USA)...

PURPOSE: To evaluate serial computed tomography (CT) findings of pulmonary mucormycosis correlated with peripheral blood absolute neutrophil count (ANC). MATERIALS AND METHODS: Between February 1997 and June 2016, 20 immunocompromised patients (10 males, 10 females; mean age, 48.9 years) were histopathologically diagnosed as pulmonary mucormycosis. On initial (n=20) and follow-up (n=15) CT scans, the patterns of lung abnormalities and their changing features on follow-up scans were evaluated, and the pattern changes were correlated with ANC changes...

OBJECTIVE: Strict blackout discipline is extremely important for all military units. To be able to effectively determine wound characteristics and perform the necessary interventions at nighttime, vision and light restrictions can be mitigated through the use of tactical night vision goggles (NVGs). The lamp of the classical laryngoscope (CL) can be seen with the naked eye; infrared light, on the other hand, cannot be perceived without the use of NVGs. The aim of the study is to evaluate the safety of endotracheal intubation (ETI) procedures in the dark under tactically safe conditions with modified laryngoscope (ML) model...

Crescentic glomerulonephritis (GN) is a devastating disease with rapidly progressive deterioration in kidney function, which, histologically, manifests as crescent formation in most glomeruli. We previously found that crescents derive from the aberrant proliferation and migration of parietal epithelial cells (PECs)/progenitor cells, and that the angiotensin (ang) II/ang II type-1 (AT1) receptor pathway may participate, together with the stromal cell-derived factor-1 (SDF-1)/CXCR4 axis, in the development of those lesions...

The combined infusion of Banisteriopsis caapi stem and Psychotria viridis leaves, known as ayahuasca, has been used for centuries by indigenous tribes. The infusion is rich in N, N-dimethyltryptamine (DMT) and monoamine oxidase inhibitors, with properties similar to those of serotonin. Despite substantial progress in the development of new drugs to treat anxiety and depression, current treatments have several limitations. Alternative drugs, such as ayahuasca, may shed light on these disorders. Here, we present time-course behavioral changes induced by ayahuasca in zebrafish, as first step toward establishing an ideal concentration for pre-clinical evaluations...

Autism spectrum disorder is a complex and genetically heterogeneous disorder, which has hampered the identification of the etiological factors in each patient and, consequently, the genetic counseling for families at risk. However, in the last decades, the remarkable advances in the knowledge of genetic aspects of autism based on genetic and molecular research, as well as the development of new molecular diagnostic tools, have substantially changed this scenario. Nowadays, it is estimated that using the currently available molecular tests, a potential underlying genetic cause can be identified in nearly 25% of cases...

Podocalyxin is an electronegative sialoglycoprotein that prevents the podocyte foot process from collapsing. The aim of this study was to detect an association between the glomerular immunohistochemical (IHC) expression of podocalyxin and the degree of podocyte effacement detected by electron microscopy, and to evaluate the role of podocalyxin IHC expression as a novel marker for disease activity in lupus nephritis (LN). METHODS: Thirty-two renal biopsies of active lupus nephritis patients were studied...

Proliferation of glomerular epithelial cells, including podocytes, is a key histologic feature of crescentic glomerulonephritis. We previously found that retinoic acid (RA) inhibits proliferation and induces differentiation of podocytes by activating RA receptor-α (RARα) in a murine model of HIV-associated nephropathy. Here, we examined whether RA would similarly protect podocytes against nephrotoxic serum-induced crescentic glomerulonephritis and whether this effect was mediated by podocyte RARα. RA treatment markedly improved renal function and reduced the number of crescentic lesions in nephritic wild-type mice, while this protection was largely lost in mice with podocyte-specific ablation of Rara (Pod-Rara knockout)...

OBJECTIVE: To assess the clinical features, pathological presentations, treatments and outcomes of lupus nephritis (LN) with anti-neutrophil cytoplasmic antibody (ANCA) positivity. DESIGN: A case-control study. METHODS: Patients (n=49) were retrospectively included from Jinling Hospital in China if presenting with biopsy-proven ANCA-positive LN between 1985 and 2008. Clinicopathological characteristics and outcomes were analysed and compared with those of a control group (n=1279)...

During a magnetopause crossing the Magnetospheric Multiscale spacecraft encountered an electron diffusion region (EDR) of asymmetric reconnection. The EDR is characterized by agyrotropic beam and crescent electron distributions perpendicular to the magnetic field. Intense upper-hybrid (UH) waves are found at the boundary between the EDR and magnetosheath inflow region. The UH waves are generated by the agyrotropic electron beams. The UH waves are sufficiently large to contribute to electron diffusion and scattering, and are a potential source of radio emission near the EDR...

BACKGROUND: Acute kidney injury (AKI) is known as an uncommon presentation in immunoglobulin A nephropathy (IgAN). The aim of our study was to analyze the clinical data and biopsy findings in IgAN patients presenting with AKI. METHODS: We performed a retrospective analysis of all subjects who had biopsy-proven IgAN and presented with AKI during June 2002 September 2015. The following data were obtained from medical records. RESULTS: A total of 15 patients of 123 patients (12...

OBJECTIVE: To evaluate the effectiveness of crescentic corneal lamellar wedge resection for the treatment of pellucid marginal degeneration (PMD) in improving refractive, visual, and corneal aberrometry. METHODS: The study included 10 eyes of 10 patients who had undergone corneal lamellar wedge resection for PMD. Pellucid marginal degeneration was diagnosed based on the clinical signs and corneal topography. The corneal aberrometry was evaluated with Sirius corneal topography...

BACKGROUND: Rheumatoid arthritis is a systemic disorder where clinically significant renal involvement is relatively common. However, crescentic glomerular nephritis is a rarely described entity among the rheumatoid nephropathies. We report a case of a patient with rheumatoid arthritis presenting with antineutrophil cytoplasmic antibody-negative crescentic glomerular nephritis. CASE PRESENTATION: A 54-year-old Sri Lankan woman who had recently been diagnosed with rheumatoid arthritis was being treated with methotrexate 10 mg weekly and infrequent nonsteroidal anti-inflammatory drugs...

The Golden Crescent region of South Asia-comprising Afghanistan, Iran, and Pakistan-is a principal global site for opium production and distribution. Over the past few decades, war, terrorism, and a shifting political landscape have facilitated an active heroin trade throughout the region. Protracted conflict has exacerbated already dire socio-economic conditions and political strife within the region and contributed to a consequent rise in opiate trafficking and addiction among the region's inhabitants. The worsening epidemic of injection drug use has paralleled the rising incidence of HIV and other blood-borne infections in the region and drawn attention to the broader implications of the growing opiate trade in the Golden Crescent...

PURPOSE: To describe a simple preoperative ink test as a novel adjunct to intrastromal keratopigmentation for post-laser peripheral iridotomy (LPI) dysphotopsias. METHODS: A surgical marking pen is applied to the area over a peripheral iridotomy before intrastromal keratopigmentation. The patient can then assess whether there is any improvement in their symptoms of dysphotopsias. Manual intrastromal keratopigmentation can then be performed using a crescent blade into the clear cornea at 50% depth and tunneled centrally to create a pocket ensuring that the peripheral iridotomy is fully occluded...

INTRODUCTION: Henoch-Schönlein Purpura (HSP; IgA vasculitis), the most common vasculitis of childhood, has a wide spectrum of clinical manifestations ranging from palpable purpura with abdominal pain and arthritis to the more morbid renal involvement. AIMS AND OBJECTIVES: To study and correlate the clinical presentation, laboratory values, skin and renal histopathology and immunofluoroscence findings in HSP.
