The first description of performing a new diagnostic procedure, cryobiopsy, in lung transplant recipients in Poland.
Three cases of patients after lung transplantation were analyzed in context of the procedure of cryobiopsy, which was performed in a hybrid room with a bronchoscopic video track and C-arm radiograph. Patients were subjected to complete anesthesia and intubated. Two or three sections with an average diameter of 5 mm were collected.
The sections were large and fully diagnostic. In all 3 described cases they brought a decisive element into diagnosis.
Cryobiopsy is a useful tool in the differential diagnosis of lesions and complications that occur after lung transplantation.

While their synthetic complexity may hinder their direct use as therapeutics, they represent tools for elucidation of suitable molecular targets and serve as inspiration for the design of simplified synthetic counterparts. Here, we review the recent use of various activity-based protein profiling methods to uncover molecular targets of ENPs. Beyond target identification, these examples also showcase further development of synthetic ligands from natural product starting points. Two examples demonstrate how ENPs can progress the emerging fields of targeted protein degradation and molecular glues. Though challenges still remain in the synthesis of ENP-based probes, and in their synthetic simplification, their potential for discovery of novel mechanisms of action makes it well worth the effort.Radical trachelectomy (RT) is a surgery for early-stage cervical cancer treatment that preserves the childbearing ability, and its use has become increasingly common worldwide. Thus, the rate of conception in women who have undergone RT is increasing. However, pregnancy after RT is associated with a higher risk of several obstetric complications such as preterm delivery, preterm premature membrane rupture, and abnormal bleeding from varices at the site of uterovaginal anastomosis. Furthermore, since RT have a residual prophylactic cerclage, it is difficult to manage first- and second-trimester miscarriages. There is little previous data on the management of pregnancy after RT. In this review article, we summarize various management methods and experiences to provide a guide to clinicians for perinatal management after RT.Clinically, ALS phenotypes depend on the areas of the body that are affected, the different degrees of involvement of upper and lower motor neurons, the degrees of involvement of other systems, particularly cognition and behavior, and rates of progression. Phenotypic variability of ALS is characteristic and can be declined on the distribution of motor manifestations but also on the presence of extra-motor signs present in a variable manner in ALS patients. Neuropathologically, ALS is defined by the loss of UMN and LMN and the presence of two representative motor neuronal cytoplasmic inclusions, Bunina bodies and 43kDa Transactivation Response DNA Binding Protein (TDP-43) - positive cytoplasmic inclusions. find more The distribution of cytopathology and neuronal loss in patients is variable and this variability is directly related to phenotypic variability. Key regulators of phenotypic variability in ALS have not been determined. The functional decrement of TDP-43, and region-specific neuronal susceptibility to ALS, may be involved. Due to the selective vulnerability among different neuronal systems, lesions are multicentric, region-oriented, and progress at different rates. They may vary from patient to patient, which may be linked to the clinicopathological variability across patients.
The present study aimed to investigate the electromyographic (EMG) indices of muscle fatigue along with biochemical marker of fatigue-that is, blood lactate-during a dynamic fatigue protocol in individuals with type 2 diabetes mellitus (T2DM) vs a healthy control group. Secondarily, it aimed to examine the association between EMG indices of muscle fatigue and blood lactate in these patients.
Thirty-four participants took part in the study 19 individuals with T2DM (age, 53.5 ± 6.85 years) and 15 age-matched healthy controls (age, 50.2 ± 3.55 years). Participants performed a dynamic fatigue protocol consisting of 5 sets of 10 repetitions each at an intensity of the 10-repetition maximum. Surface EMG of the vastus medialis and vastus lateralis muscles was recorded during the dynamic fatigue protocol, and EMG indices such as median frequency (MF), slope of MF (MF
), Dimitrov muscle fatigue spectral index, and root-mean-square were evaluated for each contraction across all the 5 sets. Blood lactate concentrations were also assessed 3 times during the fatigue protocol.
Findings revealed that EMG muscle fatigue indices such as MF, MF
, and Dimitrov muscle fatigue spectral index were significantly altered in individuals with T2DM vs healthy individuals across the sets and repetitions for both the vastus medialis (P < .001) and vastus lateralis muscles (P < .001). There was a significantly greater rise in blood lactate in individuals with T2DM than in healthy individuals (P < .001), which was not found to be associated with changes in EMG indices of muscle fatigue.
Findings suggest the existence of significantly greater fatigue in the knee extensor muscles of individuals with T2DM than healthy individuals.

We sought to identify genetic variants for AD through a family-based design using the Puerto Rican (PR) Alzheimer Disease Initiative (PRADI). Whole-genome sequencing (WGS) and parametric linkage analysis were performed for 100 individuals from 23 multiplex PRADI families. Variants were prioritized by minor allele frequency (5.1, which overlaps with an AD linkage region from two published independent studies. The region harbors C9orf72, but no expanded repeats were observed in the families. Seven variants prioritized by the PRADI families also displayed evidence for association in the PR10/66 (p less then 0.05), including a missense variant in UNC13B. Our study demonstrated the importance of family-based design and WGS in genetic study of AD.
