T-cell lymphoblastic lymphoma with extensive thrombi and cardiac thrombosis: A case report and review of literature.

Background: T-lymphoblastic lymphoma (T-LBL), a neoplasm of immature T-cell precursors or lymphoblasts, is a clinically aggressive disease. In general, patients with T-LBL have a poor prognosis and often have high-risk clinical features, such as mediastinal masses, central nervous system infiltration, or other indications of high tumor burden; however, extensive thrombi are not common.

Case Summary: A 27-year-old woman presented to the Department of General Surgery with cervical lymph node enlargement accompanied by cough, wheezing, and palpitation for 3 mo.

Active Sites in Single-Layer BiOX (X = Cl, Br, and I) Catalysts for the Hydrogen Evolution Reaction.

Although few-layer bismuth oxyhalides (BiOX, X = Cl, Br, and I) have been shown to be appropriate for photocatalytic hydrogen production, the hydrogen evolution reaction (HER) activity of BiOX is unrevealed. Herein, the origins of catalytic activity on single-layer BiOX are investigated by using the density functional theory. The grand potential calculations show that the Bi- and BiO-terminations of single-layer BiOX are stable in O-poor and O-rich environments, respectively.

Robust carbon nanotube foam for efficient electromagnetic interference shielding and microwave absorption.

Lightweight and robust carbon nanotube (CNT)/chitosan (CS) foams were assembled by a facile unidirectional freeze-drying method in this work. The CNT/CS foam exhibited an excellent electromagnetic interference (EMI) shielding effectiveness (SE) of 37.6 dB while the density was only 17.

Ancient DNA reveals that the genetic structure of the northern Han Chinese was shaped prior to 3,000 years ago.

The Han Chinese are the largest ethnic group in the world, and their origins, development, and expansion are complex. Many genetic studies have shown that Han Chinese can be divided into two distinct groups: northern Han Chinese and southern Han Chinese. The genetic history of the southern Han Chinese has been well studied.

Ancient DNA from nomads in 2500-year-old archeological sites of Pengyang, China.

Six human remains (dating approximately 2500 years ago) were excavated from Pengyang, China, an area occupied by both ancient nomadic and farming people. The funerary objects found with these remains suggested they were nomads. To further confirm their ancestry, we analyzed both the maternal lineages and paternal lineages of the ancient DNA.

Tracing the genetic history of the Chinese people: mitochondrial DNA analysis of aneolithic population from the Lajia site.

Ancient DNA analysis was conducted on the dental remains of specimens from the Lajia site, dating back 3,800-4,000 years. The Lajia site is located in Minhe county, Qinghai province, in northwestern China. Archaeological studies link Lajia to the late period of the Qijia culture, one of the most important Neolithic civilizations of the upper Yellow River region, the cradle of Chinese civilization.

[Determination of trace elements in ancient Cheshi human costa by ICP-AES].

In recent years, the study on palaeodiet is an important research in the international archaeological field. Trace elements in human bones can supply a lot of valuable information to reconstruct ancient diet. In this study, The trace elements in Bronze age Cheshi human costa from Chubeixi cemetery in shanshan, Xinjiang were determined by ICP-AES.
