The prevalence of ACC of lobar bronchial origin is lower than that of other lung malignancies, and studies investigating it are lacking. This study aimed to evaluate survival of patients with ACC of the lobar bronchus after surgical resection and to explore its prognostic factors.

Sustainable development (SD) has increasingly played a key background role in government policymaking across the world, especially for the least developed countries in Africa. Therefore, the purpose of our research is to study the SD of African countries in public life, education, and welfare, and then to help policy makers better monitor the status of sustainable development and formulate development policies in these aspects. We firstly propose a new method to assess the SD in public life, education, and welfare.

Objective: In this study, we aimed to identify the facial features of patients with cancer using the deep learning technique.
The turbulent boundary layer flow measured by two-dimensional time-resolved particle image velocimetry is analyzed using the discrete orthogonal wavelet method. The Reynolds number of the turbulent boundary layer based on the friction velocity is Re_{τ}=235. The flow field is decomposed into a number of wavelet levels which have different characteristic scales.

Objective: To observe the ultrastructure of nymphal Armillifer sp. isolated from Macaca fascicularis by using scanning electron microscope (SEM), and analyze the phylogenetic relationships based on 18S rRNA gene sequences.
Methods: The parasite samples stored in 70% alcohol were fixed by glutaraldehyde and osmium peroxide.
Six Theileria spp. from cattle, buffalo and black goat were identified in the Hubei province of China. In order to study the taxonomic status of these parasites, phylogenetic analysis of 18S rRNA genes were carried out.

Hypodermin C (HC) cDNA was amplified from recombinant pGEM - T/HC, cloned in frame with the signal sequence in yeast vector pPIC9k. The plasmid was linerarized and transformed into Pichia pastoris GS115 strain by electroporation method. Recombinant strain was screened by G418 resistant, and further confirmed by PCR.

Cryptosporidium bovis and Cryptosporidium deer-like genotype were much more prevalent in the post-weaned animals. It is not clear whether the same infection pattern also occurs in other geographic areas.
