In terms of anatomical liver sectionectomy approaches, both a central hepatectomy (CH) and major hepatectomy (MH) are feasible options for a centrally located hepatocellular carcinoma (HCC).

We retrospectively reviewed the surgical outcomes of central HCC patients who underwent CH or MH. MH includes hemihepatectomy or trisectionectomy, whereas CH involves a left medial sectionectomy, right anterior sectionectomy, or central bisectionectomy. The surgical outcomes were compared before and after propensity score matching (PSM).

A total of 233 patients were enrolled, including 132 in the CH group and 101 in the MH group. The MH group cases were pathologically more advanced and had poorer overall survival rates than the CH group. After PSM, 68 patients were selected into each group, both of which showed similar overall and recurrence-free survival outcomes. The CH group showed a tendency for a longer operation time; however, other perioperative outcomes were similar between the two groups. Multivariate analyses of our matched HCC patients revealed that the type of surgery (CH or MH) was not an independent prognostic factor. More patients in the matched CH group experienced a repeat hepatectomy for recurrence and no patients in this group underwent a preoperative portal vein embolization.

The short- and long-term surgical outcomes of CH and MH for a centrally located HCC are similar under a matched clinicopathological background. CH has the advantage of not requiring a preoperative portal vein embolization and increased chances of conducting a repeat hepatectomy for recurrence.

Cancer cells reprogram metabolic activities to meet bio-energetic, biosynthetic and redox requirements needed to sustain indefinite proliferation. In many cases, metabolic reprogramming is the result of complex interactions between genetic alterations in well-known oncogenes and tumor suppressors and epigenetic changes. While the metabolism of the two most abundant nutrients, glucose and glutamine, is reprogrammed in a wide range of cancers, accumulating evidence demonstrates that additional metabolic pathways are also critical for cell survival and growth. Proline metabolism is one such metabolic pathway that promotes tumorigenesis in multiple cancer types, including liver cancer, which is the fourth main cause of cancer mortality in the world. Despite the recent spate of approved treatments, including targeted therapy and combined immunotherapies, there has been no significant gain in clinical benefits in the majority of liver cancer patients. Thus, exploring novel therapeutic strategies and identifying new molecular targets remains a top priority for liver cancer. Two of the enzymes in the proline biosynthetic pathway, pyrroline-5-carboxylate reductase (PYCR1) and Aldehyde Dehydrogenase 18 Family Member A1 (ALDH18A1), are upregulated in liver cancer of both human and animal models, while proline catabolic enzymes, such as proline dehydrogenase (PRODH) are downregulated. Here we review the latest evidence linking proline metabolism to liver and other cancers and potential mechanisms of action for the proline pathway in cancer development.Two new strategies for the efficient synthesis of racemic 1,2,3,4-tetrahydroisoquinoline-3-phosphonic acid (TicP) (±)-2 have been developed. The first strategy involves the electron-transfer reduction of the easily obtained α,β-dehydro phosphonophenylalanine followed by a Pictet-Spengler cyclization. The second strategy involves a radical decarboxylation-phosphorylation reaction on 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (Tic). In both strategies, the highly electrophilic N-acyliminium ion is formed as a key intermediate, and the target compound is obtained in good yield using mild reaction conditions and readily available starting materials, complementing existing methodologies and contributing to the easy accessibility of (±)-2 for further research.
The magnitude of heat acclimation (HA) adaptations varies largely among individuals, but it remains unclear what factors influence this variability. This study compared individual characteristics related to fitness status and body dimensions of low-, medium-, and high responders to HA.

Twenty-four participants (9 female, 15 male; maximum oxygen uptake [[Formula see text]O
] 52 ± 9mLkg
min
) completed 10 daily controlled-hyperthermia HA sessions. Adaptations were evaluated by heat stress tests (HST; 35min cycling 1.5W kg
; 33°C, 65% relative humidity) pre- and post-HA. Low-, medium-, and high responder groups were determined based on tertiles (n = 8) of individual adaptations for resting rectal temperature (T
), exercise-induced T
rise (ΔT
), whole-body sweat rate (WBSR), and heart rate (HR).

Body dimensions (p > 0.3) and [Formula see text]O
(p > 0.052) did not differentiate low-, medium-, and high responders for resting T
or ΔT
. High WBSR responders had a larger body mass and lower body surface area-to-mass ratio than low responders (83.0 ± 9.3 vs 67.5 ± 7.3kg; 249 ± 12 vs 274 ± 15 cm
kg
, respectively; p < 0.005). Conversely, high HR responders had a smaller body mass than low responders (69.2 ± 6.8 vs 83.4 ± 9.4kg; p = 0.02). [Formula see text]O
did not differ among levels of responsiveness for WBSR and HR (p > 0.3).

Individual body dimensions influenced the magnitude of sudomotor and cardiovascular adaptive responses, but did not differentiate T
adaptations to HA. The influence of [Formula see text]O
on the magnitude of adaptations was limited.

In facioscapulohumeral muscular dystrophy (FSHD) fatigue is a major complaint. We aimed to investigate whether during isometric sustained elbow flexions, performance fatigability indexes differ in patients with FSHD with respect to healthy controls.

Seventeen patients with FSHD and seventeen healthy controls performed two isometric flexions of the dominant biceps brachii at 20% of their maximal voluntary contraction (MVC) for 2min and then at 60% MVC until exhaustion. Muscle weakness was characterized as a percentage of predicted values. Maximal voluntary strength, endurance time and performance fatigability indices (mean frequency of the power spectrum (MNF), muscle fiber conduction velocity (CV) and fractal dimension (FD)), extracted from the surface electromyogram signal (sEMG) were compared between the two groups.

In patients with FSHD, maximal voluntary strength was 68.7% of predicted value (p < 0.01). Compared to healthy controls, FSHD patients showed reduced MVC (p < 0.001; r = 0.62) and lower levels of performance fatigability, characterized by reduced rate of changes in MNF (p < 0.01; r = 0.56), CV (p < 0.05; 0.37) and FD (p < 0.001; r = 0.51) and increased endurance time (p < 0.001; r = 0.63), during the isometric contraction at 60% MVC.

A decreased reduction in the slopes of all the considered sEMG parameters during sustained isometric elbow flexions suggests that patients with FSHD experience lower levels of performance fatigability compared to healthy controls.

Habitual endurance exercise results in increased erythropoiesis, which is primarily controlled by erythropoietin (EPO), yet studies demonstrating upregulation of EPO via a single bout of endurance exercise have been equivocal. This study compares the acute EPO response to 30min of high versus 90min of moderate-intensity endurance exercise and whether that response can be upregulated via selective adrenergic receptor blockade.

Using a counterbalanced, cross-over design, fifteen participants (age 28 ± 8) completed two bouts of running (30-min, high intensity vs 90-min, moderate intensity) matched for overall training stress. A separate cohort of fourteen participants (age 31 ± 6) completed three bouts of 30-min high-intensity cycling after ingesting the preferential β
-adrenergic receptor (AR) antagonist bisoprolol, the non-preferential β
+ β
antagonist nadolol or placebo. AS2863619 Venous blood was collected before, during, and after exercise, and serum EPO levels were determined by ELISA.

No detectable EPO re, returning to baseline immediately post-exercise. Identifying the optimal mode, duration and intensity required to evoke an EPO response to exercise may help tailor exercise prescriptions designed to maximize EPO response for both performance and clinical applications.
Passive elevation of body temperature can induce an acute inflammatory response that has been proposed to be beneficial; however, it can be perceived as uncomfortable. Here, we investigate whether local cooling of the upper body during hot water immersion can improve perception without inhibiting the interleukin-6 (IL-6) response.

Nine healthy male participants (age 22 ± 1years, body mass 83.4 ± 9.4kg) were immersed up to the waist for three 60-min water immersion conditions 42°C hot water immersion (HWI), 42°C HWI with simultaneous upper-body cooling using a fan (FAN), and 36°C thermoneutral water immersion (CON). Blood samples to determine IL-6 plasma concentration were collected pre- and post-water immersion; basic affect and thermal comfort were assessed throughout the intervention.

Plasma IL-6 concentration was higher for HWI and FAN when compared with CON (P < 0.01) and did not differ between HWI and FAN (P = 0.22; pre to post, HWI 1.0 ± 0.6 to 1.5 ± 0.7pg·ml
, FAN 0.7 ± 0.5 to 1.1 ± 0.5pg·ml
, CON 0.5 ± 0.2 to 0.5 ± 0.2pg·ml
). At the end of immersion, basic affect was lowest for HWI (HWI -1.8 ± 2.0, FAN 0.2 ± 1.6, CON 1.0 ± 2.1, P < 0.02); thermal comfort for HWI was in the uncomfortable range (3.0 ± 1.0, P < 0.01when compared with FAN and CON), whereas FAN (0.7 ± 0.7) and CON (-0.2 ± 0.7) were in the comfortable range.

Local cooling of the upper body during hot water immersion improves basic affect and thermal comfort without inhibiting the acute IL-6 response.

To examine the risk factors of proximal junctional kyphosis (PJK) after surgery for adult spinal deformity (ASD) focusing on rod contour.

Sixty-three patients with ASD who underwent surgery using lateral lumbar interbody fusion and percutaneous pedicle screws were analyzed. Fixation range was from the lower thoracic spine to the pelvis in all cases. Patients were divided into two groups. The PJK group consisted of 16 patients with PJK. The non-PJK group had 47 patients without PJK. We examined various spinopelvic parameters and parameters related to rod contour.

Among the various spinal and pelvic parameters, those in the PJK group were significantly larger in terms of preoperative SVA and were significantly smaller in terms of postoperative "PI-LL." For parameters related to rod contour, the rod kyphotic curve at the thoracic spine in the PJK group was significantly less than that in the non-PJK group. The inclination of the pedicle screw at the upper instrumented vertebra (UIV) was significantly more cranial in the PJK group than in the non-PJK group.
