Multifocus microscopy enables recording of entire volumes in a single camera exposure. In dense samples, multifocus is severely hampered by background haze. Here, we introduce scalable method that incorporates optical sectioning and offers improved axial resolution capabilities. our method, dithered oblique light-sheet scans the sample volume during exposure, while fluorescence from each illumi...

Heterogamous marriages, in which partners have dissimilar attributes (e.g. by socio-economic status or ethnicity), are often at elevated risk of dissolution. We investigated the influences of heterogamy by religion and area of residence on risk of marital dissolution in Northern Ireland, a country with a history of conflict and residential segregation along Catholic-Protestant lines. We expecte...

The aim of this study is to compare the efficiency of radiopaque dye, decalcification, and histological sectioning in detection of accessory canals in mandibular 1 st molars. 30 Extracted mandibular 1 st molars were selected. The teeth selected for the study were stored in normal saline. Endodontic access openings were made using a round bur and pulp tissue was removed from the pulp chamber usi...

BACKGROUND This study compared different diamond burs and different water flow rates on the cutting efficiency of sectioning through lithium disilicate glass ceramic. METHODS The authors used a standardized cutting regimen with 4 brands of diamond burs to section through lithium disilicate glass ceramic blocks. Twelve diamonds of each brand cut through the blocks in randomized order. In the f...

The present study investigated the local arrestability of intergranular crack in high-strength martensitic steel through multi-scale three-dimensional (3D) analysis using X-ray computed tomography and focused ion beam machining (FIB)-scanning electron microscopy (SEM) serial sectioning combined with backscattering diffraction (3D EBSD). Macroscopic demonstrated discontinuous propagation cracks,...

BACKGROUND Changes to the integrity of the acromioclavicular (AC) joint impact scapulothoracic and clavicular kinematics. AC ligaments provide anterior-posterior stability, while the coracoclavicular (CC) ligaments provide superior-inferior stability and a restraint to scapular internal rotation. The purpose of this cadaveric study was to describe the effect of sequential AC and CC sectioning o...

BACKGROUND Understanding the exact contribution of the supporting ligaments to the functional integrity of the wrist is crucial for the diagnosis and treatment of carpal instabilities. The present study evaluates functional significance of the wrist ligaments with respect to carpal instabilities. MATERIALS AND METHODS Sixteen fresh cadaver wrists were dissected. Extrinsic and intrinsic ligame...

Aims: Our study was designed to find out the incidence of micrometastases in 580 cervical lymph nodes using serial sectioning and by using immunohistochemical stains CK(cytokeratin) and EMA(epithelial membrane antigen). Settings and Design: study was conducted on 30 patients who were diagnosed with head and neck carcinomas and subsequently underwent neck dissections. Patients with head and neck...

The present study tested the hypothesis that if polycystic ovary syndrome (PCOS) results from activating the noradrenergic outflow to the ovary, unilaterally sectioning the superior ovarian nerve (SON) will result in ovulation by the denervated ovary, and the restoration of progesterone (P4), testosterone (T) and estradiol (E2) normal serum level. A single 2 mg dose of estradiol valerate (EV) t...

Preterm birth is a major public health problem in terms of loss of life, long-term and short term disabilities worldwide. The process of parturition (both term and preterm) involves intensive remodelling of the extracellular matrix (ECM) in the placenta and fetal membranes by matrix metalloproteinases (MMPs). Our previous studies show reduced docosahexaenoic acid (DHA) in women delivering prete...
