d-Amino acids are important building blocks for various compounds, such as pharmaceuticals and agrochemicals. A more cost-effective enzymatic method for d-amino acid production is needed in the industry. We improved a one-pot enzymatic method for d-amino acid production by the dynamic kinetic resolution of N-succinyl amino acids using two enzymes: d-succinylase (DSA) from Cupriavidus sp. P4-10-C, which hydrolyzes N-succinyl-d-amino acids enantioselectively to their corresponding d-amino acid, and N-succinyl amino acid racemase (NSAR, EC...

Nisin-associated-sensitivity-response-regulator (NsaRS) in Staphylococcus aureus is important for its adhesion to surfaces and resistance against antibiotics, like nisin. NsaRS consists of an intra-membrane-located sensor NsaS and a cytoplasmatically-located response-regulator NsaR, which becomes activated upon receiving phosphate groups from the intra-membrane-located sensor. HYPOTHESIS: The intra-membrane location of the NsaS sensor leads us to hypothesize that the two-component NsaRS system not only senses "chemical" (nisin) but also "mechanical" (adhesion) stresses to modulate efflux of antibiotics from the cytoplasm...

BACKGROUND AND PURPOSE: Sarcopenic obesity is associated with disability, gait problems, and falls. Activities of daily living such as walking and climbing stairs are physically difficult or impossible for the individual with severe obesity. These aspects also limit participation in recreational activities or exercise programs. However, good muscle function is crucial to maintain functional independence. The objective of this study was to investigate the influence of resistance training on physical function in older, obese persons with sarcopenia...

BACKGROUND: Chronic subdural haematomas (cSDHs) have shown an increasing incidence in an ageing population over the last 20 years, while unacceptable recurrence rates of up to 30 % persist. The recurrence rate of cSDH seems to be related to the excessive neoangiogenesis in the parietal membrane, which is mediated via vascular endothelial growth factor (VEGF). This is found to be elevated in the haematoma fluid and is dependent on eicosanoid/prostaglandin and thromboxane synthesis via cyclo-oxygenase-2 (COX-2)...

OBJECTIVE: Malignant hypertension as borne out by uncontrolled hypertension with accelerated target organ damage has a variable and often dire prognosis. Loss of kidney function is a hallmark of the condition and is frequently accompanied by thrombotic microangiopathy (TMA). DESIGN AND METHOD: Here we present the case of a patient with malignant hypertension, who was successfully treated using a combination of in-label and off-label medication according to the following pathophysiological concepts: 1) Innate immunity has been identified as a player in blood pressure (BP) control, 2) the complement inhibitor eculizumab has become available for treating atypical hemolytic uremic syndrome (aHUS), which shares many features of malignant hypertension, 3) endothelin (ET) antagonism, although not currently approved for these indications, has been shown to be effective for treating proteinuria and as a possible adjunct for the treatment of resistant hypertension...

Acute pericarditis is an inflammation of the pericardium. Different etiologies are known, and can be classified in three groups: infectious, neoplastic and auto-immun. The diagnosis is based essentially on clinical signs and should be raised by position and respiratory dependent chest pain, especially when it follows a viral infection, and a pericardial friction rub on cardiac auscultation. An ECG and an echocardiography should be performed to assess the presence of a pericardial effusion. A diffuse and concave ST elevation permits the distinction with myocardial ischemia...

BACKGROUND: A differential diagnosis of persistent chronic rhinosinusitis is ASA-intolerance syndrome (AIS), also known as Aspirin®‑exacerbated respiratory disease (AERD), Samter-Trias (Samter's disease, Morbus Widal). Particularly in cases of frequent recurrency of nasal polyps in combination with bronchial asthma and hypersensitivity reactions to acetylsalicylic acid (ASA) and other nonsteroidal anti-inflammatory drugs (NSAR) can often be referred to an underlying AIS. The pathogenesis of this syndrome is attributed to a misallocation of the arachidonic acid metabolism, resulting in an increased leukotriene production...

Recent epidemiological studies show a positive association between cancer incidence and high intake of processed meat. N-nitrosamines (NAs) in these products have been suggested as one potential causative factor. Most volatile NAs (VNAs) are classified as probable human carcinogens, whereas the carcinogenicity for the majority of the non-volatile NA (NVNA) remains to be elucidated. Danish adults (15-75 years) and children (4-6 years) consume 20 g and 16 g of processed meat per day (95th percentile), respectively...

The o-succinylbenzoate synthase (OSBS) family is part of the functionally diverse enolase superfamily. Many proteins in one branch of the OSBS family catalyze both OSBS and N-succinylamino acid racemization in the same active site. In some promiscuous NSAR/OSBS enzymes, NSAR activity is biologically significant in addition to or instead of OSBS activity. Identifying important residues for each reaction could provide insight into how proteins evolve new functions. We have made a series of mutations in Amycolatopsis sp...

Catalytic promiscuity, which is the ability to catalyze more than one reaction in the same active site, is thought to facilitate the evolution of new protein functions. Although many enzymes are catalytically promiscuous, there is little direct evidence to show how promiscuous activities evolved into biological functions. We are seeking evidence for this model by studying the o-succinylbenzoate synthase (OSBS) family. Most enzymes within this family only catalyze OSBS, which is a step in menaquinone synthesis...
