BACKGROUND: Worldwide propagation of minimally invasive surgeries (MIS) is hindered by their drawback of indirect observation and manipulation, while monitoring of surgical instruments moving in the operated body required by surgeons is a challenging problem. Tracking of surgical instruments by vision-based methods is quite lucrative, due to its flexible implementation via software-based control with no need to modify instruments or surgical workflow. METHODS: A MIS instrument is conventionally split into a shaft and end-effector portions, while a 2D/3D tracking-by-detection framework is proposed, which performs the shaft tracking followed by the end-effector one...

Ag-LaFeO3 molecularly imprinted polymers (ALMIPs) were fabricated, which provided special recognition sites to methanol. Then ALMIPs fiber 1, fiber 2 and fiber 3 were prepared using filter paper, silk and carbon fibers template, respectively. Based on the observation of X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and Nitrogen adsorption surface area analyzer (BET), the structure, morphology and surface area of the fibers were characterized. The ALMIPs fibers (fiber 1, fiber 2 and fiber 3) show excellent selectivity and good response to methanol...

Classification of patients with rheumatoid arthritis (RA) as quickly as possible improves their prognosis. This reason motivates specially dedicated early arthritis (EA) clinics. Here, we have used 1062 EA patients with two years of follow-up to explore the value of anti-carbamylated protein (anti-CarP) antibodies, a new type of RA specific autoantibodies, for classification. Specifically, we aimed to determine whether the addition of anti-CarP antibodies to IgM rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies, which are helpful in RA classification, improves it or not...

Crime on the internet has grown accordingly to the increased use of the internet in everyday life. This includes illegal trading of pharmaceuticals via the internet. Trading in pharmaceuticals as "special commodities" underlies certain legal regulations in Germany, as in most other countries worldwide.Mail order trade (colloquially also known as internet trade) in pharmaceuticals requires approval of the competent regulatory authority. However, numerous illegal internet vendors of medicines present their websites to customers, purporting to be legal pharmacies and trading good and genuine medicines...

External auditory canal atresia (EACA) is a common otologic condition. Etiology can vary from congenital to acquired causes. It causes considerable difficulty to the patient. Bilateral ear canal atresia in children can lead to speech delays due to hearing impairment caused by this condition. Though easily diagnosed it is one of the most difficult conditions to treat. Acquired conditions can affect any age group. Restenosis following treatment is very common. This article focuses on the treatment of EACA due to different etiologies and emphasizes on special points of surgical treatment and follow up...

INTRODUCTION: Most centres offer laparoscopic treatment for liver hydatid cyst (LHC). There have been concerns about the management of intra-peritoneal spillage, bleeding, and cystobiliary communication (CBC) during laparoscopic surgery for LHC. CBC can exist in 13%-37% of cases of LHC. No randomised studies have compared open versus laparoscopic approach for the treatment of LHC. We specifically analysed the outcomes of laparoscopic treatment of LHC with special reference to associated biliary complications...

Measuring the eye's mechanical properties in vivo and with minimally invasive techniques can be the key for individualized solutions to a number of eye pathologies. The development of such techniques largely relies on a computational modelling of the eyeball and, it optimally requires the synergic interplay between experimentation and numerical simulation. In Astrophysics and Geophysics the remote measurement of structural properties of the systems of their realm is performed on the basis of (helio-)seismic techniques...

Almost ten years after the renaissance of the popular perovskite-type semiconductors based on lead-salts with general formula AMX3 (A=organic or inorganic cation, M=divalent metal, X=halide), many facets of photophysics continue to puzzle researchers. In this review, we shed some light on the low mobilities of charge carriers in lead-halide perovskites with special focus on the lattice properties at non-zero temperature. The polar and soft lattice leads to pronounced electron-phonon coupling, limiting carrier mobility and retarding recombination...

Sedentary broadcast-spawning marine invertebrates, which release both eggs and sperm into the water for fertilization, are of special interest for sexual selection studies. They provide unique insight into the early stages of the evolutionary succession leading to the often-intense operation of both pre- and post-mating sexual selection in mobile gonochorists. Since they are sessile or only weakly mobile, adults can interact only to a limited extent with other adults and with their own fertilized offspring...
