Salvaging high-quality genomes of microbial species from a meromictic lake using a hybrid sequencing approach.

Most of Earth's bacteria have yet to be cultivated. The metabolic and functional potentials of these uncultivated microorganisms thus remain mysterious, and the metagenome-assembled genome (MAG) approach is the most robust method for uncovering these potentials. However, MAGs discovered by conventional metagenomic assembly and binning are usually highly fragmented genomes with heterogeneous sequence contamination.

Crusted scabies with scalp involvement in an institutionalized elderly.

Scabies is a common disease and typically described as a skin condition with sparing of face and scalp in adults. However, crusted scabies is not conventional scabies. It can also affect the scalp.

sp. nov., isolated from the saline Lake Tus in Siberia.

A halotolerant, psychrotolerant and methylotrophic methanogen, strain SY-01, was isolated from the saline Lake Tus in Siberia. Cells of strain SY-01 were non-motile, cocci and 0.8-1.

The Mechanism of Onychomadesis (Nail Shedding) and Beau's Lines Following Hand-Foot-Mouth Disease.

Background: Nail changes, including onychomadesis (nail shedding) and Beau's line, following hand-foot-mouth disease (HFMD) are a common emergence at the stage of late complications of HFMD. However, the exact mechanism is still unknown. Therefore, we conducted this study to elucidate the mechanism of nail changes following HFMD.

Comprehensive Insights Into Composition, Metabolic Potentials, and Interactions Among Archaeal, Bacterial, and Viral Assemblages in Meromictic Lake Shunet in Siberia.

Microorganisms are critical to maintaining stratified biogeochemical characteristics in meromictic lakes; however, their community composition and potential roles in nutrient cycling are not thoroughly described. Both metagenomics and metaviromics were used to determine the composition and capacity of archaea, bacteria, and viruses along the water column in the landlocked meromictic Lake Shunet in Siberia. Deep sequencing of 265 Gb and high-quality assembly revealed a near-complete genome corresponding to sp.

Alopecia syphilitica.

Alopecia syphilitica is a less common manifestation of secondary syphilis. It could present with other mucocutaneous symptoms of secondary syphilis or rarely present as the only symptom of secondary syphilis, the so-called "essential syphilitic alopecia." Herein, we present a case of essential syphilitic alopecia to remind physicians, especially for sexually active patients.

Effect of mouth-opening levels on sound field gain in the ear canal.

The human external auditory canal can become deformed when the mandible moves, and this changes the sound field in the external auditory canal. This study measured the sound field gain in the external auditory canal while varying mouth-opening in three levels. The mandible was fixed at the 1/3, the 2/3, and the maximal mouth-opening levels.

Methanolobus psychrotolerans sp. nov., a psychrotolerant methanoarchaeon isolated from a saline meromictic lake in Siberia.

A psychrotolerant, methylotrophic methanogen, strain YSF-03, was isolated from the saline meromictic Lake Shira in Siberia. Cells of strain YSF-03 were non-motile, irregular cocci and 0.8-1.

Bacterial Communities of Three Saline Meromictic Lakes in Central Asia.

Meromictic lakes located in landlocked steppes of central Asia (~2500 km inland) have unique geophysiochemical characteristics compared to other meromictic lakes. To characterize their bacteria and elucidate relationships between those bacteria and surrounding environments, water samples were collected from three saline meromictic lakes (Lakes Shira, Shunet and Oigon) in the border between Siberia and the West Mongolia, near the center of Asia. Based on in-depth tag pyrosequencing, bacterial communities were highly variable and dissimilar among lakes and between oxic and anoxic layers within individual lakes.

Effects of porous-hydroxyapatite incorporated into glass-ionomer sealants.

The purpose of the present study was to evaluate the mechanical and chemical properties of a novel glass ionomer cement for use as a pit and fissure sealant containing a porous hydroxyapatite, namely, apatite ionomer cement (AIC). Control sealant samples were used Fuji III (GIC-S). The experiment sealant samples (AIC-S) consisted of porous spherical hydroxyapatite (HApS) particles added at 28 wt% to GIC-S powder.

Aliidiomarina shirensis sp. nov., a halophilic bacterium isolated from Shira Lake in Khakasia, southern Siberia, and a proposal to transfer Idiomarina maris to the genus Aliidiomarina.

Strain AIS(T), an aerobic halophilic, Gram-reaction-negative, heterotrophic bacterium isolated from the water of Shira Lake in Khakasia, southern Siberia, was characterized using a polyphasic approach. Our analysis of the 16S rRNA gene sequences showed that 'Aliidiomarina haloalkalitolerans', 'Aliidiomarina sanyensis', Idiomarina maris and AIS(T) formed a distinct lineage. The sequence similarities between AIS(T) and the type strains of species of the genera Idiomarina and Aliidiomarina were 91.

Silver-containing hydrofiber dressing is an effective adjunct in the treatment of pemphigus vulgaris.

Pemphigus vulgaris is a life-threatening autoimmune bullous dermatosis and its management represents a major challenge to medical teams. The primary treatments for pemphigus vulgaris are oral steroids and immunosuppressants, but topical approaches also play a role in disease management. Here, we report a patient with pemphigus vulgaris involving 62% of the total body surface area, with initial poor clinical response to systemic steroids and topical silver sulfadiazine therapy.

Prevalence of adult atopic dermatitis among nursing staff in a Taiwanese medical center: a pilot study on validation of diagnostic questionnaires.

Background: Atopic dermatitis (AD) is a chronic, relapsing dermatosis. Previous studies have focused mostly on pediatric patients, and investigations emphasizing adult AD have been limited.

Objective: We set out to determine the 1-year prevalence and evaluate the validity of the International Study of Asthma and Allergies in Childhood (ISAAC) and United Kingdom Working Party (UKWP) AD questionnaires of adult AD in Taiwan.

Phakomatosis cesioflammea with late-onset glaucoma and acquired nevus spilus-like lesion - 15 years of follow-up.

Phakomatosis pigmentovascularis is a very rare disease characterized by coexistence of a capillary malformation with various melanocytic lesions, including dermal melanocytosis (Mongolian spots), nevus spilus, and nevus of Ota. As of now about 200 cases have been reported, most are of Japanese origin and about half of reported cases are associated with various systemic involvement. We present a 15-year-old Taiwanese male with phakomatosis cesioflammea who developed, during adolescence, a nevus spilus-like lesion and late-onset open angle glaucoma, suggesting that long-term ophthalmic follow-up is necessary in this type of patient.

A single lesion showing features of pigmented eccrine poroma and poroid hidradenoma.

Poroid hidradenoma (PH) is a variant of poroma. This entity was defined by Abenoza and Ackerman in 1990. This neoplasm shows architectural characteristics of hidradenoma (tumor cells confined entirely within the dermis in both solid and cystic components) and cytologic characteristics of poroid neoplasm (poroid and cuticular cells, the latter showing ductal differentiation).

Alteromonas tagae sp. nov. and Alteromonas simiduii sp. nov., mercury-resistant bacteria isolated from a Taiwanese estuary.

Two mercury-resistant strains of heterotrophic, aerobic, marine bacteria, designated AT1(T) and AS1(T), were isolated from water samples collected from the Er-Jen River estuary, Tainan, Taiwan. Cells were Gram-negative rods that were motile by means of a single polar flagellum. Buds and prosthecae were produced.
