Background: Mucosa-associated lymphoid tissue (MALT) lymphoma, also known as extranodal marginal zone lymphoma, is more commonly detected in the stomach and rarely in the breast. Our study presented a clinical and pathological examination of a patient diagnosed with breast MALT lymphoma, supplemented with pertinent research, to offer guidance for the diagnosis and treatment of this condition.
People Concerns: The occurrence of breast MALT lymphoma has risen in the past decade, but its etiology, progression and treatment response are less well-studied.
A well-defined Ru(II)-PNP complex demonstrated high activity in the anti-Markovnikov hydroalkylation of nonpolarized terminal alkenes via hydrazones. Hydrazone served as a carbanion equivalent to combine with the electrophilic alkene substrate upon activation by the ruthenium catalyst, forming a new C-C bond in a concerted pathway with N as the only theoretical byproduct. Experimental and computational studies suggested the existence of a push-pull interaction that activated the alkene for hydrazone addition and then deduced the mechanism.

The sulfur poisoning mechanism of low-temperature SCR de-NO catalyst has always been one of the hot spots in academic circles. By studying the surface sulfur poisoning mechanism, low-temperature catalysts can be developed pertinently. In this paper, the mechanism of sulfur poisoning on the surface of LaMnO catalyst was studied by DFT method, and the adsorption process of sulfur oxides on the surface and its influence on SCR reaction process, as well as the morphology and decomposition process of ammonium sulfate on the surface were calculated.

In this study, the negative effects of the electrogenerated ClO were compared among four commonly used anode materials (BDD, TiO, PbO and Ru-IrO) in terms of ClO interference on the evaluation of electrochemical COD removal performance and biotoxicity. Apparently, the COD removal performance of various EO systems were highly enhanced with increasing current density in the presence of Cl, e.

To address this concern, the co-pyrolysis behavior of UF resin with pine sawdust (PS) was studied, and the adsorption properties of pyrocarbon were evaluated with Cr (VI). Thermogravimetric analysis revealed that adding a small amount of PS can improve the pyrolysis behavior of UF resin.

From the conventional viewpoint, the TiO material may be the desired particle electrodes in the 3D system since its high oxygen evolution potential favors the production of OH via HO splitting reaction at the anode side of TiO particle electrodes. In fact, the incorporation of TiO particles showed phenol degradation of 88% and COD removal of 51% within 120 min, under the optimum conditions at energy consumption of 0.

In recent years, the continuous development of electronic chips and the increasing integration of devices have led to extensive research on the thermal properties of ultrathin metallic materials. In particular, accurate characterization of their thermal transport properties has become a research hotspot. In this paper, we review the characterization methods of metallic nanomaterials, focusing on the principles of the transient electrothermal (TET) technique and the differential TET technique.

A rapid transcriptional regulatory cascade has evolved in plants in response to HS. Nuclear Factor-Y (NF-Y) complexes are critical for this mechanism, but how NF-Y complexes are regulated remains unclear.

Recent advancement in natural language processing (NLP) and medical imaging empowers the wide applicability of deep learning models. These developments have increased not only data understanding, but also knowledge of state-of-the-art architectures and their real-world potentials. Medical imaging researchers have recognized the limitations of only targeting images, as well as the importance of integrating multimodal inputs into medical image analysis.

In this study, an easy sulfite-based reduction method was developed for the first time to remove ClO from the water samples before COD determination to eliminate this interference of ClO. In this reaction system, keeping the reaction temperature of sulfite reducing ClO at 60 C was crucial for fast ClO removal rate, fixed molar [sulfite]/[chlorate] ratio value and the synchronous exhaustion of sulfite and ClO, which were of great significance for the real application of this improved COD determination method.

Combustion characteristics and reaction path of typical low calorific value biogas with variation of preheating temperature and air equivalence ratio () are discussed in this paper. Preheating can not only improve the flame propagation speed and flame temperature, but also increase the proportion of NO in the product at the end of combustion flame.
