Fertility outcomes after preconceptional laparoscopic abdominal cerclage for second-trimester pregnancy losses.

Objective(s): Cervical incompetence is an important cause of recurrent pregnancy loss, typically presenting in the second trimester with silent cervical dilation and premature delivery of the fetus. We aimed to evaluate the conception rate and time to conception or failure to conceive after preconceptional laparoscopic abdominal cerclage (LAC).

Study Design: We conducted this retrospective observational cohort study at a tertiary referral center.

The impact of a poor quality embryo on the implantation chance of a good quality one when transferred together: A study on double blastocyst transfers.

Objective: Embryo quality assessment with morphological evaluation remains the first-line method of assessment to select the best embryo for transfer. We aimed to determine if an effect of poor quality embryos on good quality ones exists, whether by a paracrine effect or an adverse endometrial influence, when they are transferred together.

Materials And Methods: We included 412 couples, who underwent intracytoplasmic sperm injection (ICSI) cycles in a tertiary IVF center.

Automated segmentation of the injured kidney due to abdominal trauma.

The objective of this study is to propose and validate a computer-aided segmentation system which performs the automated segmentation of injured kidney in the presence of contusion, peri-, intra-, sub-capsular hematoma, laceration, active extravasation and urine leak due to abdominal trauma. In the present study, total multi-phase CT scans of thirty-seven cases were used; seventeen of them for the development of the method and twenty of them for the validation of the method. The proposed algorithm contains three steps: determination of the kidney mask using Circular Hough Transform, segmentation of the renal parenchyma of the kidney applying the symmetry property to the histogram, and estimation of the kidney volume.

A New Practical Intracerebral Hematoma Volume Calculation Method and Comparison to simple ABC/2.

Aim: To find a more practical and effective formula than simple ABC/2 (sABC/2) to calculate the hematoma volume in patients with subdural and parenchymal haemorrhage.

Material And Methods: We reviewed the records of 157 patients who underwent brain computed tomography examinations for stroke from January to October 2017. Our method, sABC/2 formula, and the planimetric method (the gold standard) were used for measuring the volumes of hematoma.

Automated computer-aided diagnosis of splenic lesions due to abdominal trauma.

Background: Computer-aided detection in the setting of trauma presents unique challenges due to variations in shape and attenuation of the injured organs based on the timing and severity of the injury.  We developed and validated an automated computer-aided diagnosis algorithm to detect splenic lesions such as laceration, contusion, subcapsular hematoma, perisplenic hematoma, and active extravasation using computed tomography (CT) images in patients sustaining blunt or penetrating abdominal trauma.

Methods: We categorized the splenic pathologies into three groups: contusion/laceration, hematoma, and active extravasation.

Can balneotherapy improve the bowel motility in chronically constipated middle-aged and elderly patients?

Balneotherapy or spa therapy is usually known for different application forms of medicinal waters and its effects on the human body. Our purpose is to demonstrate the effect of balneotherapy on gastrointestinal motility. A total of 35 patients who were treated for osteoarthritis with balneotherapy from November 2013 through March 2015 at our hospital had a consultation at the general surgery for constipation and defecation disorders.

Automated segmentation of the injured spleen.

Purpose: To develop a novel automated method for segmentation of the injured spleen using morphological properties following abdominal trauma. Average attenuation of a normal spleen in computed tomography (CT) does not vary significantly between subjects. However, in the case of solid organ injury, the shape and attenuation of the spleen on CT may vary depending on the time and severity of the injury.

Constipation and faecal incontinence present as anorectal dysfunction in MS and anal manometry, colonic transit time, electromyography, and defecography can be used for assessment.

Presentation Of Case: We presented a thirty-three years old woman with rare condition of anorectal dysfunction in multiple sclerosis.

Optical phase cloaking of 700 nm light waves in the far field by a three-dimensional carpet cloak.

Transformation optics is a design tool that connects the geometry of space and propagation of light. Invisibility cloaking is a corresponding benchmark example. Recent experiments at optical frequencies have demonstrated cloaking for the light amplitude only.

Three-dimensional polarization-independent visible-frequency carpet invisibility cloak.

We miniaturize all features in a previously introduced polarization-independent three-dimensional carpet invisibility cloak by more than a factor of 2. This leads to operation wavelengths in the visible. The structures are characterized by electron and optical microscopy.

Optical microscopy of 3D carpet cloaks:ray-tracing calculations.

In a recent publication (T. Ergin et al., Science 328, 337 (2010)), three-dimensional broadband dielectric carpet cloaks have been fabricated and experimentally characterized by optical bright-field and dark-field microscopy using unpolarized light from an incandescent lamp.

Three-dimensional invisibility cloak at optical wavelengths.

We have designed and realized a three-dimensional invisibility-cloaking structure operating at optical wavelengths based on transformation optics. Our blueprint uses a woodpile photonic crystal with a tailored polymer filling fraction to hide a bump in a gold reflector. We fabricated structures and controls by direct laser writing and characterized them by simultaneous high-numerical-aperture, far-field optical microscopy and spectroscopy.

Photorealistic images of carpet cloaks.

Using home-built dedicated ray-tracing software, we simulate photorealistic images of sceneries in three dimensions including dielectric carpet cloaks--i.e., continuously varying refractive-index distributions that allow for invisibility cloaking of a bump in a metallic carpet.

Intracranial injection with KCl: an alternative method in selected cases of multifetal pregnancy reduction.

Multifetal pregnancy reduction (MFPR) offers a therapeutic option which reduces the maternal, prenatal, neonatal morbidity and mortality associated with multifetal pregnancies. In certain cases of MFPR, where difficulty is encountered in reaching the thorax due to the fetal position as well as the location of membranes and placenta, an alternative approach may be the insertion of the needle to the fetal cranium. We describe a new technique for MFPR performed by fetal intracranial injection of potassium chloride.
