this study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, abramis brama orientalis, in four stages of larval development. morphological characters including total length (tl), standard length (sl), notochord length (nl), head length (hl), head depth (hd), eye diameter (ed) and mouth width (mw) were examined from hatching time ...

Failure of the resurfaced femoral head may occur in the short term owing to femoral neck fracture or in the long term owing to aseptic loosening as a result of strain shielding. Resurfacing arthroplasties are not all the same. In particular, there is considerable debate regarding the role of the metaphyseal stem and cementing technique. This study examines the influence of various metaphyseal s...

An anatomic study was conducted on 49 dried cadaveric humeri and 24 dried cadaveric scapula to ascertain the variability of the following parameters: humeral neck angle, humeral head retroversion, humeral head medial offset, humeral head posterior offset, humeral head diameter glenoid height, glenoid width, and the glenoid height to width ratio. For verification purposes, the results of this st...

Introduction: Femur is the longest and strongest bone of human body. Its length associated with a striding gait, its strength weight muscular forces. It comprises an upper end, shaft lower end. Proximal part femur includes head, neck, greater lesser trochanters. Objectives: The present study aimed to record femoral head diameter parameters were carried out which would be help orthopedicians whi...

PURPOSE We evaluated the clinical and radiographic midterm results of primary total hip arthroplasty (THA) using a 36 mm diameter femoral head on 1st generation highly cross-linked polyethylene (HXLPE) in patients 50 years and less with minimum five year follow-up. MATERIALS AND METHODS We retrospectively reviewed 31 patients (41 hips) aged 50 years and less underwent primary THA with a 36 mm...

OBJECTIVE To analyze the association between low birth weight, head-to-abdominal circumference ratio, and insulin resistance in early life. METHOD AND RESULTS Glycated serum proteins (GSPs) were quantified at delivery in 612 Chinese mother/child pairs serving as a surrogate of maternal and fetal glycemia. Differential ultrasound examination of the fetal's body (head circumference, biparietal ...

BACKGROUND Many studies have emphasized on fetal pinna measurements and morphologic features to use this structure as an additional marker for fetal chromosomal anomaly. OBJECTIVES To assess relationship between fetal pinna length and gestation age and develop a nomogram. To assess relationship between fetal pinna length and head circumference and biparietal diameter. METHODS Fetal pinna me...

BACKGROUND Even if the benefits of collars are unclear, they remain widely used, in several femoral stem designs. This study aimed to determine whether collar size should be proportional to hip dimensions and morphology. The hypothesis was that the collar should be larger for greater stem sizes and for varus femoral necks. METHODS Computed Tomography scans of 204 healthy hips were digitally a...

Dendritic spines of rat neostriatal neurons were examined by light microscopy and high voltage stereo electron microscopy (HVEM) following selective staining by intracellular microinjection of horseradish peroxidase. Conventionally prepared material also was used for quantitative analysis of dendritic spines from serial thin sections of neostriatum. Stereo electron microscopy of semithin sectio...
