BACKGROUND: The acromioclavicular (AC) capsule is an important stabilizer against horizontal translation and also contributes to the strut function of the clavicle, which guides rotation of the scapula. To best reproduce the biomechanical properties and the complex 3-dimensional (3D) guidance of the AC joint, detailed knowledge of the contribution of each of the distinctive capsular structures is needed. Purpose/Hypothesis: To perform a detailed biomechanical evaluation of the specific capsular structures of the AC joint and their contribution to translational and rotational stability...

BACKGROUND AND OBJECTIVES: The knee joint is the most common site of osteoarthritis. While joint replacement is considered an ultimate solution, radiofrequency denervation may be contemplated in some cases. Radiofrequency ablation requires precise localization of the articular branches innervating the joint capsule. The objective of this cadaveric study was to determine the source, course, relationships, and frequency of articular branches innervating the anterior knee joint capsule. METHODS: Fifteen knees were meticulously dissected...

BACKGROUND: Management options for marginal ulcers (MU) vary from medical therapy to revision surgery. Medical therapy is often ineffective and revision surgery is associated with a high morbidity and possible recurrence. AIMS: To evaluate technical feasibility, efficacy, and safety of endoscopic management of MU by covering the ulcer bed using oversewing and/or deploying a fully covered self-expandable metallic stent (FCSEMS). METHODS: Medical records of consecutive patients who underwent endoscopic suturing and/or FCSEMS deployment for recalcitrant MU between August 2016 and June 2017 at a single academic center were reviewed...

BACKGROUND: The number of patients undergoing mastectomy and immediate breast reconstruction with tissue expanders followed by post-mastectomy radiotherapy (PMRT) is exponentially increasing. To reduce the rate of complications, in 2011, the senior author of this manuscript described the use of protective lipofilling in patients undergoing unplanned PMRT to the expander with a specific protocol aiming to decrease the rate of complications. OBJECTIVES: A study was performed to evaluate the thickness of the breast irradiated tissue to create a standard pattern of "protective" lipofilling infiltration on limited key areas that could re-establish a thickness similar to non-radiotreated tissues...

In recent years, there has been a deluge of papers linking altered microbiome compositions to a myriad of diseases. Mechanistic insight into microbial drivers of disease phenotypes is essential for translation to novel therapies. A key mechanism by which microbes influence health is immune modulation by components of their capsule and cell envelope and their metabolites. A major research focus of my laboratory is to gain mechanistic insight into which microbes modulate host immunity generally and in the context of disease...

Many microbial pathogens produce a β-(1→6)-linked poly- N -acetyl-d-glucosamine (PNAG) surface capsule, including bacterial, fungal, and protozoan cells. Broadly protective immune responses to this single conserved polysaccharide antigen in animals are possible but only when a deacetylated poly- N -acetyl-d-glucosamine (dPNAG; <30% acetate) glycoform is administered as a conjugate to a carrier protein. Unfortunately, conventional methods for natural extraction or chemical synthesis of dPNAG and its subsequent conjugation to protein carriers can be technically demanding and expensive...

Diffusion magnetic resonance imaging is a non-invasive tool increasingly used for the investigation of brain connectivity in vivo. In this paper we propose a method that allows segmentation of the brainstem to four subregions (frontopontine, motor, sensory, and reticular) based on connections to supratentorial structures, thereby eliminating the need for using anatomical landmarks within the brainstem for the identification of these subregions. The feasibility of connectivity-based brainstem segmentation was investigated in a group of healthy subjects (n =20)...

Organic-inorganic CaCO3 capsules were prepared by crystallization of CaCO3 on Pickering emulsion prepared using coacervate droplets made from thermoresponsive and degradable poly(2-methylene-1,3-dioxepane-co-2-hydroxyethyl acrylate) (poly(MDO-co-HEA)) in sole aqueous medium. The diameters of CaCO3-based Pickering emulsion could be controlled by varying several parameters: diameter of CaCO3 powders, initial polymer concentration, and copolymer composition. The CaCO3 Pickering emulsion was able to load low-molecular-weight hydrophobic substances at temperatures above the lower critical solution temperature (LCST) due to formation of polymer-concentrated phases, i...

An inflammatory fibroid polyp (IFP) is a mesenchymal tumor of the gastrointestinal tract. IFPs in the small intestine are the most frequently detected with symptoms, such as abdominal pain and tarry stool due to intussusception. Accordingly, few studies have reported jejunal IFP as a cause of occult gastrointestinal bleeding (OGIB) diagnosed via both of capsule endoscopy (CE) and double-balloon enteroscopy (DBE). A 68-year-old woman presented with a progression of anemia and a positive fecal occult blood test result...

The cardiovascular polypill or fixed dose combination pill, consisting of three, four or more drugs in a single tablet (or capsule), has been proposed as an effective and convenient therapy in both secondary and primary prevention of cardiovascular disease (CVD). Each of the drugs in the combination has a documented ability to prevent CVD events. The combined effect has been estimated to reduce risk by 75% to 80%.Since the concept was introduced 15 years ago, several polypills are available and their effects on risk factors evaluated...

The goal of this protocol is to mimic the biomechanics of physiological accommodation in a cost-efficient, practical manner. Accommodation is achieved through the contraction of the ciliary body and relaxation of zonule fibers, which results in the thickening of the lens necessary for near vision. Here, we present a novel, simple method in which accommodation is replicated by tensing the zonules connected to the lens capsule via a manual lens stretcher (MLS). This method monitors the radial stretching achieved by a lens when subjected to a consistent force and allows for a comparison of accommodating lenses, which can be stretched, to non-accommodating lenses, which cannot be stretched...

The polysaccharide capsule of Cryptococcus neoformans is the primary virulence factor and one of the most commonly studied aspects of this pathogenic yeast. Capsule size can vary widely between strains, has the ability to grow rapidly when introduced to stressful or low nutrient conditions, and has been positively correlated with strain virulence. For these reasons, the size of the capsule is of great interest to C. neoformans researchers. The growth of the C. neoformans capsule is induced during phenotypic testing to help understand the effects of different treatments on the yeast or size differences between strains...

Ovarian transplantation was first conducted at Utah State University in 1963. In more recent work, heterochronic transplantation of mammalian ovaries is being used to investigate the health-protective effects of young ovaries in young females. The current procedures employ an orthotopic transplantation method, where allogenic ovaries are transplanted back to their original position in the ovarian bursa. This is in contrast to the more commonly used heterotopic transplantation of ovaries/ovarian tissue subcutaneously or under the kidney capsule...
