Abstract
Vedolizumab (VDZ) is a first-line treatment in ulcerative colitis (UC) that targets the α4β7- mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1) axis. To determine the mechanisms of action of VDZ, we examined five distinct cohorts of patients with UC. A decrease in naïve B and T cells in the intestines and gut-homing (β7+) plasmablasts in circulation of VDZ-treated patients suggested that VDZ targets gut-associated lymphoid tissue (GALT). Anti-α4β7 blockade in wild-type and photoconvertible (KikGR) mice confirmed a loss of GALT size and cellularity because of impaired cellular entry. In VDZ-treated patients with UC, treatment responders demonstrated reduced intestinal lymphoid aggregate size and follicle organization and a reduction of β7+IgG+ plasmablasts in circulation, as well as IgG+ plasma cells and FcγR-dependent signaling in the intestine. GALT targeting represents a previously unappreciated mechanism of action of α4β7-targeted therapies, with major implications for this therapeutic paradigm in UC.

Abstract
Targeting the α4β7-MAdCAM-1 axis with vedolizumab (VDZ) is a front-line therapeutic paradigm in ulcerative colitis (UC). However, mechanism(s) of action (MOA) of VDZ remain relatively undefined. Here, we examined three distinct cohorts of patients with UC (n=83, n=60, and n=21), to determine the effect of VDZ on the mucosal and peripheral immune system. Transcriptomic studies with protein level validation were used to study drug MOA using conventional and transgenic murine models. We found a significant decrease in colonic and ileal naïve B and T cells and circulating gut-homing plasmablasts (β7+) in VDZ-treated patients, pointing to gut-associated lymphoid tissue (GALT) targeting by VDZ. Murine Peyer's patches (PP) demonstrated a significant loss cellularity associated with reduction in follicular B cells, including a unique population of epithelium-associated B cells, following anti-α4β7 antibody (mAb) administration. Photoconvertible (KikGR) mice unequivocally demonstrated impaired cellular entry into PPs in anti-α4β7 mAb treated mice. In VDZ-treated, but not anti-tumor necrosis factor-treated UC patients, lymphoid aggregate size was significantly reduced in treatment responders compared to non-responders, with an independent validation cohort further confirming these data. GALT targeting represents a novel MOA of α4β7-targeted therapies, with major implications for this therapeutic paradigm in UC, and for the development of new therapeutic strategies.

Abstract
The repeated evolutionary specialization of distantly related insects to cardenolide-containing host plants provides a stunning example of parallel adaptation. Hundreds of herbivorous insect species have independently evolved insensitivity to cardenolides, which are potent inhibitors of the alpha-subunit of Na+,K+-ATPase (ATPα). Previous studies investigating ATPα-mediated cardenolide insensitivity in five insect orders have revealed remarkably high levels of parallelism in the evolution of this trait, including the frequent occurrence of parallel amino acid substitutions at two sites and recurrent episodes of duplication followed by neo-functionalization. Here we add data for a sixth insect order, Orthoptera, which includes an ancient group of highly aposematic cardenolide-sequestering grasshoppers in the family Pyrgomorphidae. We find that Orthopterans exhibit largely predictable patterns of evolution of insensitivity established by sampling other insect orders. Taken together the data lend further support to the proposal that negative pleiotropic constraints are a key determinant in the evolution of cardenolide insensitivity in insects. Furthermore, analysis of our expanded taxonomic survey implicates positive selection acting on site 111 of cardenolide-sequestering species with a single-copy of ATPα, and sites 115, 118 and 122 in lineages with neo-functionalized duplicate copies, all of which are sites of frequent parallel amino acid substitution. This article is part of the theme issue 'Convergent evolution in the genomics era: new insights and directions'.

Abstract
Background Nearly half of all patients with Parkinson's disease (PD) utilize some form of complementary therapy often identified on the Internet and frequently not reported to their physicians. Treating physicians are sometimes unaware of such treatments, including their rationale, mechanisms, potential efficacy, and potential adverse effects. Methods Methods for this study included systematic Internet search of products recommended for PD, medical literature review to determine scientific rationale, any evidence of efficacy, and potential risks. Results A large number of complementary therapies are recommended for patients with PD, generally falling into the following categories: dietary and nutritional; chelation; and physical. Most have reasonable justifications based on mechanism of action and current theories on causes of neurodegeneration in PD, but few have documented evidence of benefit. Fortunately, most have few risks and side effects, although some are very expensive. The protein redistribution diet has substantial evidence of symptomatic benefit. Some antioxidative or -inflammatory supplements, aerobic exercise, Tai chi, and dance and music therapy have preliminary evidence of symptomatic benefit or potential neuroprotective effects, but more research is needed to establish efficacy. Conclusions Patients with PD are faced with many recommendations for complementary therapies. Physicians should know about these in order to have informed discussions with their patients. Some deserve further study.

Abstract
Dopaminergic drugs can cause augmentation during the treatment of restless legs syndrome (RLS). We previously reported that sudden withdrawal of dopaminergic treatment was poorly tolerated. We now report our experience with gradual withdrawal of the dopaminergic drug during the drug substitution process using a retrospective chart review with comparison to previous data. Seven patients with RLS and dopaminergic drug-induced augmentation were treated with a gradual withdrawal of the offending drug and replacement with an alternative medication. Compared to sudden withdrawal, measured outcomes were similar but gradual tapering was better tolerated. We conclude that for augmentation in RLS, gradual tapering of the augmentation-inducing dopaminergic drug is better tolerated than sudden withdrawal. The optimal approach to treating augmentation has not been established and may differ between patients. Further study with direct comparison of strategies and a larger patient population is needed to confirm our preliminary observations.

Abstract
The comprehensive management of proximal hip fractures in elderly patients requires dedicated and responsive teamwork. Elderly patients often present with several comorbidities and the immediate treatment of a fracture has to optimize both medical therapy and analgesic control in order to reduce surgical and anesthetic complications and to preserve as much cognitive functioning as possible. The elderly are uniquely exposed to complications related to bed rest, delirium and postoperative cognitive dysfunction (POCD), which appear to be independent factors of morbidity. Anesthetic management that includes good perioperative pain management can influence the patient's inflammatory response and possibly decrease the incidence of POCD. The best choice of surgical treatment depends on the type of fracture as well as the patient's age and medical condition. However, the type of anesthesia management, which includes neuraxial blocks, peripheral nerve blocks and/or general anesthesia, has to be tailored towards generated the best outcome. We present a review from a surgical and anesthetic perspective on the most common perioperative issues in proximal fracture repair.

Abstract
The Harlow Center for Biological Psychology (HCBP) has a cohort of rhesus monkeys that were exposed to low concentrations of lead acetate in utero or as infants. The lead-exposed animals have been followed for 19 years and have developed four cases of inguinal hernia (males), three cases of endometriosis (females), and one case of immunoblastic lymphoma (male). Retrospective analysis of the data from the original lead-exposed cohort indicates that there is a significant association between lead exposure and the development of inguinal hernia (P=.04). Endometriosis was not significantly associated with lead exposure (P=.36). A case control study also was done to determine the significance of neonatal lead exposure as a risk factor for the development of inguinal hernia and endometriosis. The risk of developing inguinal hernia was significantly increased in lead-exposed animals (OR=20.0, P=.009). The association between endometriosis and lead exposure was also strong (OR=10.13, P<.001). No unmatched variables were associated with inguinal hernia, including body weight, history of diarrhea, constipation, or intussusception. No unmatched variables were highly associated with endometriosis, including body weight, age at first parity, and history of stillbirths. However, parity and the number of stillbirths were associated with lead exposure (P=.011 and P=.041, respectively). There was an association between endometriosis and a history of hysterotomy (OR=2.09) but it was not statistically significant (P=.38). No other cases of lymphoma in unexposed animals were identified using HCBP animal health records. These data indicate that early lead-exposed rhesus monkeys may develop illnesses later in life, especially inguinal hernia and endometriosis, more frequently than unexposed monkeys. Studies of human populations with early lead exposure are warranted to determine their incidence of inguinal hernia, endometriosis, and hematologic neoplasia.

Abstract
mRNA for the alpha-subunit of CaMKII is abundant in dendrites of neurons in the forebrain (Steward, 1997). Here we show that tetanic stimulation of the Schaffer collateral pathway causes an increase in the concentration of alpha-CaMKII in the dendrites of postsynaptic neurons. The increase is blocked by anisomycin and is detected by both quantitative immunoblot and semiquantitative immunocytochemistry. The increase in dendritic alpha-CaMKII can be measured 100-200 micrometer away from the neuronal cell bodies as early as 5 min after a tetanus. Transport mechanisms for macromolecules from neuronal cell bodies are not fast enough to account for this rapid increase in distal portions of the dendrites. Therefore, we conclude that dendritic protein synthesis must produce a portion of the newly accumulated CaMKII. The increase in concentration of dendritic CaMKII after tetanus, together with the previously demonstrated increase in autophosphorylated CaMKII (Ouyang et al., 1997), will produce a prolonged increase in steady-state kinase activity in the dendrites, potentially influencing mechanisms of synaptic plasticity that are controlled through phosphorylation by CaMKII.

Abstract
The
archie
[1] system is a replicated, centralized directory server for all Anonymous FTP sites in the Internet. This centralized approach has not scaled well. The
march
[2] system provides an alternate solution, using IP Multicast to distribute directory queries directly to FTP hosts.
march
suffers from highly redundant broadcast messages during expanding-disc search. We propose a solution to the problem of multicast flooding during expanding-disc searches by utilizing an automatically-configured hierarchy of query servers. This system, dubbed
MASH
, confines the multicast flooding primarily to those nodes at the frontier of each new search radius. We provide a mechanism and protocol for building a self-organizing, two-level hierarchy of
MASH
servers. We also provide an experimental implementation built on
march
[5].

Abstract
Interfacial shear strength between poly(methyl methacrylate) (PMMA) bone cement and cancellous bone was measured in bone samples from human proximal femora. Samples were prepared with fresh cement-bone, fresh cement inside a mantle of existing cement and with fresh cement-revised bone surfaces. Push-out tests to measure shear strength caused failure only at bone-cement interfaces; revised bone interfaces were 30 per cent weaker (P < 0.02) than primary interfaces. The clinical relevance is that revision of cemented joint arthroplasties may necessitate removal of components with sound cement-bone fixation. The practice of removing all traces of PMMA cement may not yield the optimal fixation; adhesion of fresh cement to freshly prepared surfaces of the existing cement might also be considered where circumstances are favourable.

Abstract
Isolated dislocation of the tarsal navicular is a rare injury that is not mentioned in standard orthopedic textbooks and described only once in the English literature. Because of the rarity of this condition, the best means of treatment has not been established. A patient with this unusual dislocation was recently diagnosed and treated. Open reduction was eventually required, which was followed by the development of ischemic necrosis of the navicular.

Abstract
The effects of pancreatic intraductal infusions of the surface active pancreatic ductogram enhancing agent, polyoxyethylene hydrogenated castor oil, were studied in the dog. Moderately high pressure retrograde infusions of 5 per cent polyoxyethylene hydrogenated castor oil into the main pancreatic duct resulted in pancreatitis-like changes significantly greater than those seen in the saline solution control group. These changes persisted despite buffering of the agent to physiologic pH and the elimination of nonphysiologically high pressure by direct ductal perfusion. Similar inflammatory changes were associated with ductal perfusion using oleic and, to a lesser degree, ricinoleic-fatty acids at concentrations of 10(-4) molar sufficient to account for the titratable acidity of 5 per cent polyoxyethylene hydrogenated castor oil. It is postulated that residual-free fatty acids may play some role in polyoxyethylene hydrogenated castor oil related toxicity. The surface active properties of the agent may also be involved. Caution and further research are recommended prior to widespread use of the agent in endoscopic retrograde pancreatography.
