OBJECTIVE: The aim of our study was to investigate the relationship among age, sex, body mass index (BMI), serum lipid profiles, blood glucose (BG), and bone mineral density (BMD), making an assessment of the risk of osteoporosis. MATERIALS AND METHODS: A total of 1,035 male and 3,953 female healthy volunteers (aged 41-95 years) were recruited by an open invitation. The basic information, including age, sex, height, weight, waistline, hipline, menstrual cycle, and medical history, were collected by a questionnaire survey and physical examination...

BACKGROUND AND PURPOSE: Preterm neonates are at risk for neurodevelopmental impairment, but reliable, bedside-available markers to monitor preterm brain growth during hospital stay are still lacking. The aim of this study was to assess the feasibility of corpus callosum-fastigium length as a new cranial sonography marker for monitoring of preterm brain growth. MATERIALS AND METHODS: In this longitudinal prospective cohort study, cranial ultrasound was planned on the day of birth, days 1, 2, 3, and 7 of life; and then weekly until discharge in preterm infants born before 29 weeks of gestational age...

OBJECTIVE: The pathogenesis of syringomyelia associated with Chiari malformation type I (CM-I) is unclear. Theories of pathogenesis suggest the cerebellar tonsils may obstruct CSF flow or alter pressure gradients, or their motion might act as a piston to increase CSF pressure in the spinal subarachnoid space. This study was performed to measure cerebellar tonsillar and hindbrain motion in CM-I and assess the potential contributions to syrinx formation. METHODS: Sixty-four CM-I patients and 25 controls were retrospectively selected from a clinical database, and all subjects had undergone cardiac-gated cine balanced fast-field echo MRI...

A new species of the genus Platydecticus is described based on adult male and female specimens and the egg. The new species, Platydecticus diaguita, inhabits the Andes Range at 27º S latitude, above 3000 m elevation. Both sexes are easily identifiable by genital morphology characters and by the external characters of the fastigium of the vertex and the reduced number of spines in the hind tibia. It is also the smallest species described for the genus.

The monotypic genus Cleostratoides gen. nov. (type species Cleostratoides exoticus sp. nov. from Vietnam) is described in the subfamily Metrodorinae. New genus is closely related to the genera Mazarredia Bolívar, 1887, Xistrella Bolívar, 1909, Pseudoxistrella Liang, 1991, Orthotettixoides Zheng, 1998 and Bermania Storozhenko, 2012, but easily distinguished from all of them by the lateral ocelli situated just under fastigium of vertex and by the antennal sockets placed distinctly above the lower margin of eyes...

Tropical Vochysiaceae includes mainly trees, and also shrubs and subshrubs. Three genera and seven species are present in the Brazilian state of Santa Catarina. The pollen morphology of six species of trees, belonging to three genera of the Vochysiaceae A. St-Hil. family, was studied. Herbaria samples were obtained, processed and treated by standard methods. The pollen grain morphology of Callisthene, Qualea and Vochysia is distinct. Medium sized pollen grains occur in Vochysia species, and small ones in Callisthene and Qualea...

We performed endoscopic dissections of the roof of the fourth ventricle in eight fresh human cadaveric heads to characterize the endoscopic anatomy of the roof of the fourth ventricle and the anatomical configuration of the structures forming its roof. We also made three-dimensional (3D) silicone casts of the fourth ventricle in seven formalin-fixed specimens to evaluate the 3D configuration of the structures that create the roof of the fourth ventricle. The roof of the fourth ventricle can be divided into three zones...

Since 1980s, the rapid development of tissue engineering and stem cell research has pushed regenerative medicine to a new fastigium, and regenerative medicine has become a noticeable research field in the international biology and medicine. In China, about 100 million patients need repair and regeneration treatment every year, while the number is much larger in the world. Regenerative medicine could provide effective salvation for these patients. Both Chinese Academy of Sciences and Chinese Academy of Engineering have made roadmaps of 2010-2050 and 2011-2030 for regenerative medicine...

OBJECTIVE: To investigate the influence of overexpression of manganese superoxide dismutase (MnSOD) of stria marginal cells (MCs) of the rat cochlea by the recombinant adeno-associated viruses of the serotypes 2 (AAV2) mediated gene-delivery for hydrogen peroxide-induced oxidative stress in vitro. METHOD: Primary cultures of MCs were infected using rAAV2-MnSOD-EGFP at dosage of multiplicity of infection (MOI) 10(1)v x /cell and using rAAV2-EGFP as control. The expression of MnSOD in MCs was examined using western blot and the activity of MnSOD was determinated by colorimetric assays...

RATIONALE AND OBJECTIVES: Anterior/posterior commissure reference system (AC/PC reference system) and the fastigium/ventricular floor plane reference system (FFL/VFL reference system) are two reference systems used in the stereotactic localization of the invisible nuclei of the brainstem in magnetic resonance (MR) images. This study investigated the variation of the midsagittal brainstem in relation to the AC/PC and VFL/FFL reference systems with respect to age and gender. MATERIALS AND METHODS: High-resolution T1-weighted structural MR images were acquired from 64 adults (age range 21-60 years, 32 males and 32 females)...

According to the survey conducted from winter and spring algal blooms, the changes of water quality and characteristics of Daning River of Three Gorges Reservoir (TGR) were studied. The results suggested that during the period of winter algal blooms centered on Tangjia bay in Daning river, chlorophyll a (Chl-a) had a wide range (the rates of (Chl-a)max and (Chl-a)min is 260). The contents of total nitrogen (TN), total phosphorus (TP) and potassium permanganate index were at very high levels because of bioaccumulation from algal blooms, but the values of dissolved oxygen (DO) and pH were very low...

The dengue cases studied during this epidemic were, as a whole, typical examples of the disease. The onset was sudden, often of a violent character, ushered in with severe headache and backache, vague pains throughout the body, and fever ranging from 101-105 degrees F. On the 2nd or 3rd day a maculopapular eruption appeared, generally on the neck, chest, and arms, but sometimes more widely disseminated. In most instances the fever remained for 3 or 4 days, after which it dropped to normal to rise again in 24 to 48 hours...

AIM: To observe the changes of the number of NKT cells in spleens and livers of induced model of experimental autoimmune encephalomyelitis (EAE), and to study the role NKT cells play in the immunoregulation of EAE. METHODS: C57BL/6 mice were immunized with MOG (35-55) peptide and received clinical evaluation daily. The mice were sacrificed at the fastigium and the splenic and hepatic lymphocytes were isolated. The changes of NKT cells in normal and EAE C57BL/6 mice were detected by flow cytometry...

Mesenchymal stem cells (MSCs) are potential sources of cells for tissue repair. However, little information is available about the time course of homing and differentiation of systemically delivered MSCs after acute myocardial ischemia (MI). In the present study, MSCs were isolated from male rat bone marrow and expanded in vitro. Female rats were divided randomly into three groups. Three hours after coronary ligation, the transplanted group received an infusion of MSCs through the tail vein; at the same time, a coronary-ligated control group was injected with culture medium, and a normal (unligated) group received MSCs...

The present study aimed to determine the role of tissue injury in migration of mesenchymal stem cells (MSCs) intravenously transplanted into heart and to establish experimental basis for improving stem cell therapy in its targeting and effectiveness. MSCs were isolated from bone marrow of male Sprague-Dawley rats and purified by density centrifuge and adhered to the culture plate in vitro. Female rats were divided randomly into four groups. Myocardial ischemia (MI) transplanted group received MSCs infusion through tail vein 3 h after MI and compared with sham-operated group or normal group with MSCs infusion, or control group received culture medium infusion...
