Somatic hypermutation and isotype switch recombination occur in germinal center B cells, are linked to transcription, and are similarly affected by deficiency in MutS homologue (MSH)2. Class-switch recombination is abrogated by disruption of genes encoding components of the catalytic subunit of DNA-dependent protein kinase (DNA-PK(cs))/Ku complex and likely involves nonhomologous end joining (NHEJ

Background: Concurrent chemoradiotherapy is standard treatment for limited stage small-cell lung cancer (SCLC). Twice-daily thoracic radiotherapy of 45 Gy in 30 fractions is considered to be the most effective schedule. The aim of this study was to investigate whether high-dose, twice-daily thoracic radiotherapy of 60 Gy in 40 fractions improves survival. Methods: This open-label, randomised, phas

Candida albicans is a commensal fungus that causes systemic infections in immunosuppressed patients. In order to deal with the changing environment during commensalism or infection, C. albicans must reprogram its proteome. Characterizing the stress-induced changes in the proteome that C. albicans uses to survive should be very useful in the development of new antifungal drugs. We studied the C. al

PREVENTIVE VACCINATION IS SUCCESSFULLY PRACTISED TODAY AGAINST TWO NEOPLASTIC DISEASES OF DOMESTIC ANIMALS: fibropapillomatosis of cattle and Marek's disease of chickens (a lymphoproliferative disease). Also it may soon be possible to immunize cats against lymphosarcoma. This memorandum describes these diseases and the immunological reactions involved. It also mentions a number of other tumours th

Cutibacterium acnes (C. acnes) is a gram-positive bacterium and a member of the human skin microbiome. Despite being the most abundant skin commensal, certain members have been associated with common inflammatory disorders such as acne vulgaris. The availability of the complete genome sequences from various C. acnes clades have enabled the identification of putative methyltransferases, some of the

This study proposes a novel design of binders for polycrystalline cubic boron nitride (PcBN) cutting tool materials. Well-known binder phases TiC and TiN were combined with transitional metal nitrides ZrN, VN, and HfN. Performance screenings of longitudinal turning Inconel 718 and AISI 316 L highlighted the superior performance of PcBN materials with mixed TiC-ZrN and TiC-VN binders. These two sys

Gastric cancer is a dominating cause of cancer-associated mortality with limited therapeutic options. Here, we show that syndecan-4 (SDC4), a transmembrane proteoglycan, is highly expressed in intestinal subtype gastric tumors and that this signature associates with patient poor survival. Further, we mechanistically demonstrate that SDC4 is a master regulator of gastric cancer cell motility and in

Visual information can be integrated in prominence perception, but most available evidence stems from controlled experimental settings, often involving synthetic stimuli. The present study provides evidence from spontaneously produced head gestures that occurred in Swedish television news readings. Sixteen short clips (containing 218 words in total) were rated for word prominence by 85 adult volun

Soil is an interface of the lithosphere, biosphere, hydrosphere and atmosphere that provides a habitat for microbial growth. The microbial biomass forms an integral part of the soil. The physiological potential and diversity of the microbial communities in soils are strongly associated with the physicochemical properties of soils. The biotic and abiotic characteristics determine the structure and

This chapter focuses on communication-centered change research and its implications for public sector organizations. It focuses on the organizational level and the communication processes through which changes are enacted. Special attention is given to coworkers and how they make sense in times of changes. Sensemaking processes play a crucial role in organizational changes; if managers and employe

Circular Economy regulation is rapidly adopted at different levels of governance, including municipalities, private and industry standards, national law and supranational standard-setting. There are increasing demands from policymakers, businesses and civil society for theoretical insights and more knowledge on the effects of policies and laws ('policy learning'). However, despite this mounting in

Increased shale gas extraction through hydraulic fracturing and its distribution through shale gas pipelines have brought about innumerable socioeconomic consequences, both tangibly and intangibly. Evidence remains unclear on what are the impacts of shale gas developments on property values. By employing a mixed method approach, combining original data collected in the Marcellus Shale through inte

Denna avhandling undersöker skapandet och omvandlingen av offentliga platser i Hongkong, en stad som är genomsyrad av nyliberala ideal och som under senare år har kännetecknats av betydande försämringar när det gäller demokratiska rättigheter och friheter. Som ett resultat av den nyliberala kapitalismens expansion har kommodifieringen av det urbana rummet inte bara förvärrats utan också blivit merThis thesis explores the production and transformation of public spaces in Hong Kong, a city that is steeped in neoliberal ideals and has seen substantial deterioration in terms of democratic rights and freedoms in recent years. As a result of the expansion of neoliberal capitalism, commodification of urban space has not only exacerbated, but also become more far-reaching and indiscriminate. While

Premature prelabor rupture of the fetal membranes affects about 3% of pregnancies. The cause is usually infection, especially at earlier gestations. The prognosis and the risks of delivery are both much worse at earlier gestations. Before viable pregnancy, termination may be offered. Once the fetus is viable, steroids to mature the fetal lungs and antibiotics to reduce infection are the mainstays

A high non-specific binding of immunoglobulins to plastic surfaces was noted with a number of rat sera, when tested in an indirect 125I-labeled protein-A assay for detection of cell-surface-bound rat immunoglobulins of various classes and IgG subclasses. This type of non-specific binding was found with all types of Ig. The degree of binding varied with the type of test plate used and fluctuated wi

Neurotensin regulates both satiety and breast cancer growth in the experimental setting, but little is known about its role in the development of breast cancer or cardiometabolic disease in humans.

The αE integrin chain CD103 identifies a subset of migratory dendritic cells (DCs) in the gut, lung, and skin. To gain further understanding of the function of CD103(+) DCs in regulating adaptive immunity in vivo, we coupled ovalbumin (OVA) to the CD103 antibody M290 (M290.OVA). Intraperitoneal injection of M290.OVA induced OVA-specific CD8(+) and CD4(+) T-cell proliferation in lymph nodes (LNs) o

Serum paraoxonase 1 (PON1) is a native lactonase capable of promiscuously hydrolyzing a broad range of substrates, including organophosphates, esters, and carbonates. Structurally, PON1 is a six-bladed β-propeller with a flexible loop (residues 70-81) covering the active site. This loop contains a functionally critical Tyr at position 71. We have performed detailed experimental and computational a
