Genetic diversity and differentiation analysis reveals geographical structure characteristics of Dermatophagoides farinae (Acari: Pyroglyphidae).

Dermatophagoides farinae (Acari: Pyroglyphidae) has been reported as one of the major sources of indoor allergens that trigger allergic disease in humans. In this study, the genetic diversity and differentiation of nine geographic populations of D. farinae were investigated by analyzing mitochondrial and nuclear genes (COI, Cytb, COI+Cytb, and ITS).

A rapid identification method for common astigmatid species based on multiplex polymerase chain reaction.

Astigmatid mites are economically significant pests of stored products and sources of inhalant allergens causing allergic rhinitis and asthma worldwide. The morphological identification of astigmatid mites at the species level is often a difficult task due to their small size, phenotypic similarity and lack of diagnostic characters. We used multiplex polymerase chain reaction (PCR) to identify astigmatid mite species, which could complement the morphological data for the species-specific identification of mites.

Longitudinal hematologic and immunologic variations associated with the progression of COVID-19 patients in China.

Background: Crucial roles of hematologic and immunologic responses in progression of coronavirus disease 2019 (COVID-19) remain largely unclear.

Objective: We sought to address the dynamic changes in hematologic and immunologic biomarkers and their associations with severity and outcomes of COVID-19.

Methods: A retrospective study including 548 patients with COVID-19 with clarified outcome (discharged or deceased) from a national cohort in China was performed.

Risk Factors of Fatal Outcome in Hospitalized Subjects With Coronavirus Disease 2019 From a Nationwide Analysis in China.

Background: The novel coronavirus disease 2019 (COVID-19) has become a global health emergency. The cumulative number of new confirmed cases and deaths are still increasing out of China. Independent predicted factors associated with fatal outcomes remain uncertain.

Clinical characteristics and outcomes of hospitalised patients with COVID-19 treated in Hubei (epicentre) and outside Hubei (non-epicentre): a nationwide analysis of China.

Background: During the outbreak of coronavirus disease 2019 (COVID-19), consistent and considerable differences in disease severity and mortality rate of patients treated in Hubei province compared to those in other parts of China have been observed. We sought to compare the clinical characteristics and outcomes of patients being treated inside and outside Hubei province, and explore the factors underlying these differences.

Methods: Collaborating with the National Health Commission, we established a retrospective cohort to study hospitalised COVID-19 cases in China.

Comorbidity and its impact on 1590 patients with COVID-19 in China: a nationwide analysis.

Background: The coronavirus disease 2019 (COVID-19) outbreak is evolving rapidly worldwide.

Objective: To evaluate the risk of serious adverse outcomes in patients with COVID-19 by stratifying the comorbidity status.

Methods: We analysed data from 1590 laboratory confirmed hospitalised patients from 575 hospitals in 31 provinces/autonomous regions/provincial municipalities across mainland China between 11 December 2019 and 31 January 2020.

First molecular evidence of Anaplasma spp. co-infection in stray dogs from Anhui, China.

Anaplasma species are obligate intracellular pathogens that threaten the health of both humans and animals worldwide. This study aimed to determine the prevalence of Anaplasma species in stray dogs in Anhui Province, China. Blood samples from 201 apparently healthy stray dogs were collected from August 2017 to January 2018, and Anaplasma spp.

De novo sequence of the mitochondrial genome of Tyrophagus putrescentiae (Acari: Sarcoptiformes) including 22 tRNA sequences and the largest non-coding region.

In this study, we de novo sequenced and analyzed the circular mitochondrial genome (mitogenome) of Tyrophagus putrescentiae. It was 14,156 bp long and contained a complete set of 37 genes, contrary to the initial published sequences; it included 22 tRNA sequences and the largest non-coding region. The mtDNA gene order of T.

Clinical Characteristics of Coronavirus Disease 2019 in China.

Background: Since December 2019, when coronavirus disease 2019 (Covid-19) emerged in Wuhan city and rapidly spread throughout China, data have been needed on the clinical characteristics of the affected patients.

Methods: We extracted data regarding 1099 patients with laboratory-confirmed Covid-19 from 552 hospitals in 30 provinces, autonomous regions, and municipalities in mainland China through January 29, 2020. The primary composite end point was admission to an intensive care unit (ICU), the use of mechanical ventilation, or death.

Molecular evidence of coinfection of Anaplasma species in small ruminants from Anhui Province, China.

The species of the genus Anaplasma are obligate intracellular pathogens that threaten the health of both humans and animals. In this study, we investigated the presence of Anaplasma phagocytophilum, A. ovis and A.

[Human skin infestation caused by : a case report].

Our study reports a case of acarodermatitis caused by . By morphological observations, the mites seized were identified as (deutonymph) which could attack humans resulting in acarodermatitis characterized with the symptoms of papules and blisters in different degrees. The patient was treated with 15% calamine lotion and anti-inflammatory and antipruritic drugs.

Invasive Epithelioid Angiomyolipoma with Tumor Thrombus in the Inferior Vena Cava: A Case Report and Literature Review.

Renal angiomyolipoma (AML) is a benign tumor. However, rare cases of renal AML demonstrate aggressive behaviors such as tumor thrombus extension into the inferior vena cava (IVC). We successfully treated a case of epithelioid AML in the right kidney involving the IVC.

beta-Keratins in crocodiles reveal amino acid homology with avian keratins.

The DNA sequences encoding beta-keratin have been obtained from Marsh Mugger (Crocodylus palustris) and Orinoco Crocodiles (Crocodylus intermedius). Through the deduced amino acid sequence, these proteins are rich in glycine, proline and serine. The central region of the proteins are composed of two beta-folded regions and show a high degree of identity with beta-keratins of aves and squamates.
