Decreased awareness of memory declines in mild cognitive impairment (MCI) has been linked to structural or functional changes in a wide gray matter network; however, the underlying white matter pathway correlations for the memory awareness deficits remain unknown. Moreover, consistent findings have not been obtained regarding the cognitive basis of disturbed awareness of memory declines in MCI. Due to the methodological drawbacks (e.g., correlational analysis without controlling confounders related to clinical status, a problem related to the representativeness of the control group) of previous studies on the aforementioned topic, further investigation is required. To addressed the research gaps, this study investigated white matter microstructural integrity and the cognitive correlates of memory awareness in 87 older adults with or without mild cognitive impairment (MCI). The patients with MCI and healthy controls (HCs) were divided into two subgroups, namely those with normal awareness (NA) and poor awarenell, the results indicated that mnemonic anosognosia was not sufficient to explain the memory awareness deficits observed in the patients with MCI. Our brain imaging findings also support the concept of anosognosia for memory deficit as a disconnection syndrome in MCI.Histone lysine demethylase 4D (KDM4D), also known as JMJD2D, plays an important role in cell proliferation and survival and has been associated with several tumor types. KDM4D has emerged as a potential target for the treatment of human cancer. Here, we reported crystal complex structures for two KDM4D inhibitors, OWS [2-(1H-pyrazol-3-yl)isonicotinic acid] and 10r (5-hydroxy-2-methylpyrazolo[1,5-a]pyrido[3,2-e]pyrimidine-3-carbonitrile), which were both determined to 2.0 Å. OWS is a newly discovered KDM4D inhibitor (IC50 = 4.28 μM) and the critical pharmacophores of this compound are confirmed by the complex structure. Compound 10r is a KDM4D inhibitor reported by us previously. To clarify the binding mode in more detail, the crystal structure was determined and the comparison analysis revealed unique interactions that had never been observed before. Overall, our data provide new structural insights for rational design and offer an opportunity for optimization of KDM4D inhibitors.Pancreatic cancer is a digestive tract malignancy characterized by an occult onset and rapid progression. The genetic heterogeneity of pancreatic cancer is closely related to its highly malignant biological behavior. The myelin and lymphocyte protein 2 (MAL2) is upregulated in multiple cancers at the transcriptional level. However, the exact role of MAL2 in pancreatic cancer remains elusive. In this study, we demonstrated that MAL2 protein and mRNA levels were upregulated in pancreatic cancer. TGF-beta inhibitor MAL2 overexpression was significantly associated with poor prognosis in patients with pancreatic cancer. We further showed that MAL2 interacted with IQGAP1 to increase ERK1/2 phosphorylation levels, which promoted pancreatic cancer progression. Therefore, these results suggest that MAL2 could be a novel therapeutic target for pancreatic cancer.
Passive mechanical properties of the paraspinal muscles are important to the biomechanical functioning of the spine. In most computational models, the same biomechanical properties are assumed for each paraspinal muscle group, while cross-sectional area or fatty infiltration in these muscles have been reported to differ between the vertebral levels. Two important properties for musculoskeletal modeling are the slack sarcomere length and the tangent modulus. This study aimed to investigate the effect of vertebral level on these biomechanical properties of paraspinal muscles in a rat model.

The left paraspinal muscles of 13 Sprague-Dawley rats were exposed under anesthesia. Six muscle biopsies were collected from each rat three from multifidus (one per each of the L1, L3, and L5 levels) and similarly three from longissimus. Each biopsy was cut into two halves. From one half, two to three single muscle fibers and two to six muscle fiber bundles (14±7 fibers surrounded in their connective tissue) were extractsignificantly different between the three spinal levels (p=0.13 for multifidus and p=0.49 for longissimus). In both muscle groups, the slack sarcomere lengths were not different among the spinal levels except for multifidus fibers (p=0.02). Collagen I area fraction in muscle fascicles averaged 6.8% for multifidus and 5.3% for longissimus and was not different between the spinal levels.

The results of this study highlighted that the tangent modulus, slack sarcomere length, and collagen I content of the lumbar paraspinal muscles are independent of spinal level. This finding provides the basis for the assumption of similar mechanical properties along a paraspinal muscle group.

Fracture risk curves related to vertical loading at individual lumbar spinal levels can be used to assess the protective ability of new injury mitigation equipment. The objectives of this study were to derive fracture risk curves for the lumbar spine under high rate compression and identify how specimen-specific attributes and lumbar spinal level may influence fracture risk. In this study, we tested a sample of three-vertebra specimens encompassing all spinal levels between T12 to S1 in high-rate axial compression. Each specimen was tested with a non-injurious load, followed by a compressive force sufficient to induce vertebral body fracture. During testing, bone fracture was identified using measurements from acoustic emission sensors and changes in load cell readings. Following testing, the fractures were assessed using computed tomographic (CT) imaging.
