Research on spatial carving method of glutenite reservoir based on opacity voxel imaging.

The glutenite reservoir in an exploration area in eastern China is well-developed and holds significant exploration potential as an important oil and gas alternative layer. However, due to the influence of sedimentary characteristics, the glutenite reservoir exhibits strong lateral heterogeneity, significant vertical thickness variations, and low accuracy in reservoir space characterization, which affects the reasonable and effective deployment of development wells. Seismic data contains the three-dimensional spatial characteristics of geological bodies, but how to design a suitable transfer function to extract the nonlinear relationship between seismic data and reservoirs is crucial.

Analysis of the Ability of a Distal Tibial Anatomical Locking Plate to Capture the Distal Tibial Fragments in Patients with Pilon Fractures.

Objective: Although pilon fractures are rare in clinical practice, they are difficult to treat because of their complexity. Effective fixation of the fracture fragment is the key to the treatment of pilon fractures. Plate osteosynthesis is common clinically, but there are many types of plates and the evaluation of the effect of fixation plates is not comprehensive.

A retrospective comparison of double-hooked locking plates versus non-locking plates in minimally invasive percutaneous plate osteosynthesis for the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures.

Background: Surgical approach and fixation material are crucial in the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures. This study compared the efficacy of double-hooked locking plates and anatomic plates in minimally invasive percutaneous plate osteosynthesis (MIPPO) for the treatment of comminuted distal fibular fractures accompanied by tibial Pilon fractures.

Methods: Clinical data were collected from 96 patients diagnosed with comminuted distal fibular fractures accompanied by tibial Pilon fractures who had undergone MIPPO.

Astragalus-Saffron-Rhubarb Mixture Delays the Progress of Diabetic Nephropathy in db/db Mice.

Objective: This study aimed to investigate the protective effect of astragalus-saffron-rhubarb mixture (Bao'shen recipe, BSR) on diabetic nephropathy (DN) in db/db mice and preliminarily explore the possible underlying mechanism.

Methods: A total of 125 8-week-old male db/db mice with DN were randomly divided into five groups: model group, irbesartan group and high-, medium- and low doses of BSR group, while 25 male db/m mice were used as a blank control. At 8, 12, 16, 20, and 24 weeks of feeding, the animals were sacrificed and blood as well as urine samples were collected for blood glucose, urea nitrogen, creatinine and urinary albumin excretion rate (UAER) measurement via blood glucose meter or corresponding detection kits, respectively.

Protein disulfide isomerase inhibits endoplasmic reticulum stress response and apoptosis via its oxidoreductase activity in colorectal cancer.

Protein disulfide isomerase (PDI), a principal endoplasmic reticulum resident oxidoreductase chaperone, is known to play a role in malignancies. This study aims to explore the molecular mechanism by which PDI regulates endoplasmic reticulum stress and the apoptosis signaling pathway in colorectal cancer (CRC). We determined the expression of PDI in CRC tissues and adjacent normal tissues.

[A new "turn-on" fluorescent probe for visual detection of hydrogen sulfide].

Thin layer chromatography coupled with surface-enhanced Raman scattering as a facile method for on-site quantitative monitoring of chemical reactions.

By coupling surface-enhanced Raman spectroscopy (SERS) with thin layer chromatography (TLC), a facile and powerful method was developed for on-site monitoring the process of chemical reactions. Samples were preseparated on a TLC plate following a common TLC procedure, and then determined by SERS after fabricating a large-area, uniform SERS substrate on the TLC plate by spraying gold nanoparticles (AuNPs). Reproducible and strong SERS signals were obtained with substrates prepared by spraying 42-nm AuNPs at a density of 5.

A novel cobalt(II) coordination polymer with an unusual four-connected 4(2).6(3).8 topology.

In the cobalt(II) coordination polymer poly[[(mu(2)-benzene-1,3-dicarboxylato){mu(2)-1,1'-[2,2'-oxybis(ethane-2,1-diyl)]di-1H-imidazole}cobalt(II)] monohydrate], {[Co(C(10)H(14)N(4)O)(C(8)H(4)O(4))].H(2)O}(n), two crystallographically distinct Co(II) cations are four-coordinated by N(2)O(2) donor sets in distorted tetrahedral geometries. The Co(II) centers are connected by benzene-1,3-dicarboxylate (m-BDC) anions, giving two types of linear chains, which are further joined via meso-helical 1,1'-[2,2'-oxybis(ethane-2,1-diyl)]di-1H-imidazole ligands to yield a thick two-dimensional slab.
