Unusual forms

Acute hypocalcemia is generally caused by a sudden drop in serum calcium ion and presents with a mild or severe form of tetany. Even though the occurrence of hypocalcemia is well documented with certain drugs such as calcium chelators, bisphosphonates, and cisplatin, it is a very unusual and poorly documented adverse event with cimetidine and nifedipine.

The only contributing factor to the formation of the intraabdominal abscess was a screening colonoscopy with polypectomy, which might have caused micro-perforations in the colon with the seeding of Streptococcus constellatus. The occurrence of intraabdominal abscess following a colonoscopy is very rare, and requires a high index of suspicion in patients who present with sepsis following colonoscopies.

Chromatin loops form a basic unit of interphase nuclear organization, with chromatin loop anchor points providing contacts between regulatory regions and promoters. However, the mutational landscape at these anchor points remains under-studied. Here, we describe the unusual patterns of somatic mutations and germline variation associated with loop anchor points and explore the underlying features influencing these patterns.

Previous studies showed that the majority of developmental genes are devoid of DNA methylation at promoters even when they are repressed. Such hypomethylated regions at developmental genes are unusually large and extend well beyond proximal promoters, forming DNA methylation valleys (DMVs) or DNA methylation canyons.

Comparison of 54 M–Si–M′–X species is carried out using quantum mechanical ab initio and DFT computations at B3LYP/6-311++G**, QCISD(T)/6-311++G**, and CCSD(T)/6-311++G** levels of theory (M = Li, Na, K; M′ = Be, Mg, Ca, and X = F, Cl, Br). All triplet species with M = K appear more linear than their corresponding ones with Li and Na. The electronegativity reactivity descriptor for each halogen (X = F, Cl, Br) is used as a tool to evaluate the interrelated properties of these silylenes.

Damage to the adult central nervous system often leads to long-term disruptions in function due to the limited capacity for neurological recovery. The central nervous system of the Mediterranean field cricket, Gryllus bimaculatus, shows an unusual capacity for compensatory plasticity, most obviously in the auditory system and the cercal escape system. In both systems, unilateral sensory disruption leads the central circuitry to compensate by forming and/or strengthening connections with the contralateral sensory organ.

Bamboo is an important member of the family Poaceae and has many inflorescence and flowering features rarely observed in other plant groups. It retains an unusual form of perennialism by having a long vegetative phase that can extend up to 120 years, followed by flowering and death of the plants. In contrast to a large number of studies conducted on the annual, reference plants Arabidopsis thaliana and rice, molecular studies to characterize flowering pathways in perennial bamboo are lacking.

Wuchereria bancrofti is a human parasitic worm (Filariworm) that is the major cause of lymphatic filariasis. It is one of the three parasitic worms, together with Brugia malayi and B. timori, that infect the lymphatic system to cause lymphatic filariasis. These filarial worms are spread by a variety of mosquito vector species. The usual form presentation of the disease is as hydrocele, acute or chronic lymphatic obstruction or subclinical microfilaremia.

Oocyte mitochondria are highly dynamic and exhibit frequent fission and fusion. Those are clustered in the cytoplasm of previtellogenic oocytes which prepare for different synthetic activities for successful reproductive investment. In contrast, mitochondrial abundance is less in the male gametic lineage. The spermatocytes and the nurse cells in the testis have an unusual type of mitochondria, nebenkern which is formed by the fusions of number of mitochondria. A completely different type of mitochondrion is discovered in the flagellum of the spermatozoa.

The serotype a-specific polysaccharide antigen ofActinoba-cillus actinomycetemcomitansis an unusual sugar, 6-deoxy-D-talose.Guanosinediphosphate (GDP)-6-deoxy-D-talose is the activated sugar nucleotide form of 6-deoxy-D-talose, which has been identified as a constituent of only a few microbial polysaccharides. In this paper, we identify two genes encoding GDP-6-deoxy-D-talose synthetic enzymes, GDP-a-D-mannose 4,6-dehydratase and GDP-4-keto-6-deoxy-D-mannose reductase, in the gene cluster required for the biosynthesis of serotype a-specific polysaccharide anti-gen from A.

HAVE YOU EVER LIFTED UP A BOARD that has been lying on a lawn for a few weeks and noticed that the grass growing underneath was much paler and spindlier than the surrounding grass? The reason this happens is that the board is opaque, keeping the underlying grass in darkness. Seedlings grown in the dark have a pale, unusually tall and spindly appearance. This form of growth, known as etiolated growth, is dramatically different from the stockier, green appearance of seedlings grown in the light (Figure 17.1). Given the key role of photosynthesis in plant metabolism, one might be tempted...

In some event detection applications, events of interest occur over a relatively small proportion of the total time: e.g. alarm generation in surveillance systems, and extrac- tive summarization of raw video events. The automatic de- tection of temporal events that are relevant, but whose oc- currence rate is either expected to be very low or cannot be anticipated at all, constitutes a problem which has recently attracted attention in computer vision and multimodal pro- cessing under an umbrella of names (abnormal, unusual, or rare events) [17, 19, 6].

A structural motif called the small exterior hydrophobic cluster (SEHC) has been proposed to explain the stabilizing effect mediated by solvent-exposed hydrophobic residues; however, little is known about its biological roles. Unusually, in D 5 -3-ketosteroid isomerase from Pseudomonas putida biotype B (KSI-PI) Trp92 is exposed to solvent on the protein surface, forming a SEHC with the side-chains of Leu125 and Val127.

To test thioredoxin resistance to oxidizing free radicals, we have studied the one-electron oxidation of wild-type thio-redoxin and of two forms with the point mutations D30A and W35A, using azide radicals generated byc-ray or pulse radiolysis. The oxidation patterns of wild-type thioredoxin and D30A are similar. In these forms, Trp35 is the primary target and is
repaired by one-electron reduction; first by intramolecular electron transfer from tyrosine, and then fromother residues. Conversely, duringoxidationofW35A, Trp13 is poorly reactive.
