A 58-year-old man underwent laparoscopy-assisted distal gastrectomy (LADG) with Billroth I gastroduodenostomy due to early gastric cancer. During surgery, the perigastric vessels were ligated with Hem-o-Lok clips. Esophagogastroduodenoscopy (EGD) 6 months later showed a fungating mass at the anastomosis site. Repeat EGD 1 year after LADG showed a Hem-o-Lok clip at the fungating mass lesion. Bec...

In this paper, we describe how a dynamic regulatory process is necessary to restrict microvilli to the apical aspect of polarized epithelial cells. We found that local phosphocycling regulation of ezrin, a critical plasma membrane-cytoskeletal linker of microvilli, was required to restrict its function to the apical membrane. Proteomic approaches and ribonucleic acid interference knockdown iden...

BACKGROUND Gastroesophageal varices are present in approximately 50% of patients with liver cirrhosis. The aim of this study was to evaluate liver stiffness measurement (LSM), Fib-4, Forns Index and Lok Score as noninvasive predictors of esophageal varices (EV). METHODS This prospective study included 65 patients with HCV-related liver cirrhosis. All patients underwent routine laboratory test...

This paper deals with the structural modeling of a family of similar, real structures taking into account uncertainties and modeling errors. The concept of Lack Of Knowledge (LOK), first introduced in [1,2], consists in globalizing the various sources of errors by means of internal variables, called the LOK variables, defined over an interval whose upper and lower bounds follow probabilistic la...

On Lok is a pioneering nonprofit organization that has delivered services to the frail and elderly since its founding in 1971. The agency began as a grassroots effort focused on improving the health care available to older adults living independently in the community. Over its 40-year history, On Lok has evolved into a $70 million nonprofit human service organization with a national reputation ...

Still today, some of the phenomena which occur in structural dynamics cannot be described, even using a properly updated model: some uncertainties remain. This paper presents the basic concepts of a new theory which uses the concept of Lack of Knowledge (LOK) to model the uncertainty using two bounds of the energy in each substructure. The inverse problem, which consists in determining the Lack...

PURPOSE We introduce our transient vascular occlusion technique that uses a vessel loop and Hem-o-Lok clips in laparoscopic partial nephrectomy. MATERIALS AND METHODS From March 2009 to March 2011, 15 consecutive patients underwent laparoscopic partial nephrectomy. All operations were performed by a single surgeon using the transperitoneal approach. The transient vascular occlusion technique ...

We developed a novel low-radiation-absorbent lok-bar (HM-bar) that is used to secure the immobilizers to the couch. The aim of this study was to investigate the X-ray scattering and absorption properties of the HM-bar in computed tomography (CT) simulation and radiotherapy dose delivery using the Varian Exact™ lok-bar (VL-bar) as a benchmark. CT images were obtained with or without lok-bar, and...

he roots of PACE (the Program of All-inclusive Care for the Elderly) stretch back several decades. In the early 1970s, clinicians and administrators at On Lok, a community organization deeply rooted in San Francisco’s ChineseAmerican community, recognized the limitations of a system of senior care built around Medicare’s and Medicaid’s traditional approach of reimbursing providers for an approv...

Until now only six out of the 51 species which constitute the genus Packera (Weber and LoK ve, 1981) had been studied chemically (Pettit et al., 1980; Bohlmann et al., 1981; McCoy et al., 1983; Zalkow et al., 1988; PeH rez et al., 1991; Bah et al., 1994). In order to contribute to the chemistry of the genus, we decided to study Packera coahuilensis (Grenm.) C. Je!rey (MEXU 781268) and Packera b...
