The wireless capsule has been used to measure physiological parameters in the gastrointestinal tract where communication from in-body to external receiver is necessary using a miniaturized antenna with high gain and onmidirectional radiation pattern. This paper presents a meandered conformal antenna with center frequency of 433 MHz for a wireless link between an in-body capsule system and an ex-body receiver system. The antenna is wrapped around the wireless capsule, which provides extra space for other circuits and sensors inside the capsule as well as allows it having larger dimensions compared to inner antennas...

In this study, the dibutyl phthalate (DBP) binding properties of a DBP-tolerant bacterium (B. cepacia) were characterized in terms of adsorption kinetics and isotherm. Living and nonliving cells both exhibited rapid removal of DBP, achieving more than 80% of maximum sorption within 30 min of contact and reached the equilibrium after 3 h. The adsorption isotherms were well fitted with the Sips model and the nonliving cells have greater biosorption capacity and affinity for DBP than the living cells. Furthermore, the absence of an active mechanism dependent on metabolism implied that the DBP bioaccumulation by living cells was mainly attribute to passive surface binding...

BACKGROUND: Past reports have shown the tendency of posterior pelvic tilt to increase over time after total hip arthroplasty (THA). We have hypothesized that the volume and extent of released joint capsule may influence the change in postoperative pelvic tilt. This study was conducted to ascertain whether surgical approach during THA (posterior or anterior) has an effect on postoperative changes in pelvic tilt. METHODS: We conducted a retrospective review of 81 hips in 60 patients...

The traditional taxonomy of the genus Chloromyxum Mingazzini, 1890 has been intensively challenged to be paraphyletic by recent ribosomal DNA (rDNA)-based phylogenetic analysis. Undersampling to get rich sequence data to infer more scientific phylogenetic relationships makes scientists conservatively assign all non-marine elasmobranch-infecting species as Chloromyxum sensu lato. Although complex ridge pattern on the spore surface observed by scanning electron microscopy was thought to be critical for the identification of Chloromyxum species, insufficient data also prevent this ultrastructural data to be a valid taxonomic feature for this genus...

Context • In the folk medicine of Mediterranean countries and in ancient Ayurveda, Punica granatum seeds (ie, pomegranate seeds) have been used for treatment of various disorders, including those that nowadays are classified as menopausal symptoms (MSs). Pomegranate seed oil (PSO) from those seeds mainly contains unsaturated fatty acids such as γ-linoleic acid and linolenic acid, but it also includes phytoestrogens. It is, therefore, regarded as a promising option for treating MSs today. Objectives • The study intended to investigate the safety and effectiveness of PSO as a defined P granatum seed oil for patients with MSs...

Green, all-polysaccharide based microcapsules with mechanically robust capsule walls and fast, stimuli-triggered and switchable permeability behaviour show great promise in applications based on selective and timed permeability. Taking cue from nature, the build-up and composition of plant primary cell wall inspired the capsule wall assembly, because the primary cell walls in plants exhibit high mechanical properties despite being in a highly hydrated state, primarily owing to cellulose microfibrils. The microcapsules (16 ± 4 µm in diameter) were fabricated using the Layer-by-Layer technique on sacrificial CaCO3 templates, using plant polysaccharides (pectin, cellulose nanofibers and xyloglucan) only...

Temporary single cell coating is a useful tool for cell processing, allowing manipulation of cells to prevent cell attachment and agglomeration, before re-establishing normal cell function. In this paper, a speckled coating method using a known polycation (poly-L-lysine, PLL) is described to induce cell surface electrostatic charges on three different cell types - two bone cancer cell lines and fibroblasts. The morphology of the PLL speckled coating on the cell surface, internalization and metabolization of the polymer, and prevention of cellular aggregations are reported...

BACKGROUND: Essential Tremor (ET) is a common movement disorder that can be disabling. Initial treatment is in the form of medical therapies. Patients with medically refractory ET seek surgical intervention which include radiofrequency thalamotomy, deep brain stimulation, and radiosurgical thalamotomy. Radiosurgical thalamotomy is a minimally invasive surgical option which is especially valuable for elderly and high surgical risk patients. OBJECTIVE: The purpose of this study was to retrospectively analyze the outcomes of stereotactic radiosurgery for patients suffering from medically refractory essential tremor...

BACKGROUND: The B-B Score is a straightforward kinematic shoulder function score including only two movements (hand to the Back + lift hand as to change a Bulb) that demonstrated sound measurement properties for patients for various shoulder pathologies. However, the B-B Score results using a smartphone or a reference system have not yet been compared. Provided that the measurement properties are comparable, the use of a smartphone would offer substantial practical advantages. This study investigated the concurrent validity of a smartphone and a reference inertial system for the measurement of the kinematic shoulder function B-B Score...

BACKGROUND: Currently, various techniques are used to overcome postoperative pain after total knee arthroplasty. A local analgesic infiltration with periarticular multimodal drug injection (PMDI) is favorable because of its simplicity, safety, and efficacy. The present study compared the efficacy of a PMDI at the anterior vs posterior compartments. METHODS: Forty-six patients were randomized to receive the PMDI at either the anterior or posterior compartment, with the contralateral knee receiving the PMDI at the opposite compartment...

Chromobacterium violaceum is an opportunistic pathogen of mammals that produces characteristic violet pigment in bacterial culture. We report pneumonia and septicaemia caused by C. violaceum in a horse. Necropsy examination was performed on a 3-year-old Quarter Horse stallion with a history of recurrent episodes of pneumonia, fever, dyspnoea and sanguineous nasal discharge. The lungs were not collapsed, but they contained dark red foci mixed with white areas, and multiple nodules of firm consistency. Within the liver and kidney there were randomly distributed, multifocal, white pinpoint lesions (0...

We describe a technique for performing safe phacoemulsification of a Morgagnian cataract using the intraocular lens (IOL) scaffold. An IOL scaffold has been used in cases in which posterior capsule rupture has occurred, leaving nonemulsified nuclear pieces. The scaffold provides a barrier that prevents the nuclear fragments from falling posteriorly into the vitreous cavity. Our technique uses the IOL as a scaffold to prevent the vulnerable posterior capsule from rupturing during nuclear emulsification in Morgagnian cataract...

In this paper, we demonstrate velocity-level closed-loop control of a tethered magnetic capsule endoscope that is actuated via serial manipulator with a permanent magnet at its end-effector. Closed-loop control (2 degrees-of-freedom in position, and 2 in orientation) is made possible with the use of a real-time magnetic localization algorithm that utilizes the actuating magnetic field and thus does not require additional hardware. Velocity control is implemented to create smooth motion that is clinically necessary for colorectal cancer diagnostics...
