Autosomal recessive Emery Dreifuss muscular dystrophy (AR-EDMD) is rare, with few reports in the medical literature. We describe the first cases of AR-EDMD and autosomal dominant familial partial lipodystrophy (FPLD) in the Hutterite population resulting from homozygous or heterozygous R482Q mutations in the lamin A/C gene (LMNA). Heterozygosity for LMNA R482Q mutation causes FPLD, which is associated with increased risk of hyperlipidemia and hypertension. The overall carrier frequency of the R482Q mutation in Dariusleut and Leherleut Hutterites in Alberta was found to be 1.45%. Homozygosity for this mutation has not been previously reported and here resulted in a combination of generalized lipodystrophy and EDMD. Knowledge that the LMNA R482Q mutation is present in this population is important for genetic counseling, surveillance, and management of the associated disorders.

To provide a critical contemporary review of daily PDE5-inhibitor (PDE5-I) use in urological and nonurological conditions. PDE5-Is can be taken up to once a day. However, at present only tadalafil is approved for use in both erectile dysfunction (ED) and benign prostate hyperplasia (BPH) with lower urinary tract symptoms (LUTS). Evolving research in penile rehabilitation, Peyronie's disease, male infertility, pulmonary arterial hypertension, muscular dystrophy and Raynaud's phenomenon shows these therapeutic areas may also benefit from PDE5i therapy. This review examines the role of chronic PDE5 inhibition in ED, BPH-LUTS and other therapeutic targets which may shape our clinical practice in the years to come.

The first decades of the new medical genetics (1980 to 2000) were marked by resounding successes, with the identification of the genes responsible (when defective) for muscular dystrophy, cystic fibrosis, or Huntington's disease, to name justa few of the several thousand Mendelian genetic conditions whose causes are now known. In contrast, the search for genes involved in common disorders such as diabetes,hypertension, schizophrenia, or autism failed miserably in the 1990s, with inconsistent and conflicting results--although the strong genetic component of these diseases (that also involve environmental factors) was (and still is) beyond doubt. From 2000 on,thanks to huge progress in genomic knowledge, technology, and analytical methods, it became possible to reliably identify genes influencing the risk of complex conditions,using the so-called GWAS (Genome-Wide Association Study) approach. Yet many problems remain, such as the vexing question of the "missing heritability," or the difficulty of translating these scientific results into genetic tests with real clinical validity and utility. Autism is one of the cases in which a strong genetic component has been demonstrated, but where the search for causative genes remains difficult and attempts at developing valid genetic tests have failed, because of the many genes involved and possibly of the heterogeneity of the condition.

Inherited heart conditions are the most common cause of sudden cardiac death in those under the age of 35 and the leading cause of non-traumatic death in young athletes. Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease affecting 1 in 500 of the population. Some patients may exhibit severe left ventricular hypertrophy, others may show nothing more than an abnormal ECG. Left ventricular hypertrophy most commonly manifests in the second decade of life. Sudden death is rare and usually affects patients in the first three decades whereas older patients present with heart failure, atrial fibrillation and stroke. Arrhythmogenic right ventricular cardiomyopathy is a rare, autosomal dominant heart muscle disorder which affects between 1 in 1,000 and 1 in 5,000 of the population. Dilated cardiomyopathy (DCM) is characterised by a dilated left ventricle with impaired function that cannot be explained by ischaemic heart disease, hypertension or valvular heart disease. At least 25% of cases of DCM are familial. DCM may be associated with multisystem conditions such as muscular dystrophy. Chemotherapy and certain other drugs, alcohol abuse and myocarditis may also lead to a dilated and poorly contracting left ventricle. In many cases the first manifestation of an inherited cardiomyopathy can be a sudden cardiac arrest. Other presentations include chest pain or breathlessness during exertion, palpitations and syncope. In many of the cardiomyopathies, the diagnosis can be made with a standard ECG and echocardiogram. However if the diagnosis is not certain or the cardiologist wishes to look at the heart structure in greater detail, a cardiac MRI may be performed.

Specific respiratory muscle training (IMT) improves the function of the inspiratory muscles. According to literature and clinical experience, there are 3 established methods: 1.) resistive load 2.) threshold load and 3.) normocapnic hyperpnea. Each training method and the associated devices have specific characteristics. Setting up an IMT should start with specific diagnostics of respiratory muscle function and be followed by detailed individual introduction to training. The aim of this review is to take a closer look at the different training methods for the most relevant indications and to discuss these results in the context of current literature. The group of neuromuscular diseases includes muscular dystrophy, spinal muscular atrophy, amyotrophic lateral sclerosis, paralysis of the phrenic nerve, and injuries to the spinal cord. Furthermore, interstitial lung diseases, sarcoidosis, left ventricular heart failure, pulmonary arterial hypertension (PAH), kyphoscoliosis and obesity are also discussed in this context. COPD, asthma, cystic fibrosis (CF) and non-CF-bronchiectasis are among the group of obstructive lung diseases. Last but not least, we summarize current knowledge on weaning from respirator in the context of physical activity.

Blood mononuclear cells consist of T cells and monocyte derived cells. Beside immunity, the blood mononuclear cells belong to the complex tissue control system (TCS), where they exhibit morphostatic function by stimulating proliferation of tissue stem cells followed by cellular differentiation, that is stopped after attaining the proper functional stage, which differs among various tissue types. Therefore, the term immune and morphostatic system (IMS) should be implied. The TCS-mediated morphostasis also consists of vascular pericytes controlled by autonomic innervation, which is regulating the quantity of distinct tissues in vivo. Lack of proper differentiation of tissue cells by TCS causes either tissue underdevelopment, e.g., muscular dystrophy, or degenerative functional failures, e.g., type 1 diabetes and age-associated diseases. With the gradual IMS regression after 35 years of age the gonadal infertility develops, followed by a growing incidence of age-associated diseases and cancers. Without restoring an altered TCS function in a degenerative disease, the implantation of tissue-specific stem cells alone by regenerative medicine can not be successful. Transfused young blood could temporarily restore fertility to enable parenthood. The young blood could also temporarily alleviate aging diseases, and this can be extended by substances inducing IMS regeneration, like the honey bee propolis. The local and/or systemic use of honey bee propolis stopped hair and teeth loss, regressed varicose veins, improved altered hearing, and lowered high blood pressure and sugar levels. Complete regression of stage IV ovarian cancer with liver metastases after a simple elaborated immunotherapy is also reported.

The LMNA gene contains 12 exons and encodes lamins A and C by alternative splicing within exon 10. While mutations in lamin A specific residues cause several diseases including lipodystrophy, progeria, muscular dystrophy, neuropathy, and cardiomyopathy, only three families with mutations in lamin C-specific residues are reported with cardiomyopathy, neuropathy, and muscular dystrophy so far. We now report two brothers with juvenile-onset generalized lipodystrophy due to a lamin C-specific mutation. The proband, a 23-year-old Caucasian male was reported to have generalized lipodystrophy at 3 weeks of age, developed diabetes, hypertriglyceridemia, hypertension and liver problems and died with complications of cirrhosis, and kidney failure. His younger brother, a 37-year-old Caucasian male developed generalized lipodystrophy around 2 years of age and was diagnosed with diabetes, hypertriglyceridemia, fatty liver, and hypertension at 36 years of age. Their father also died of end stage renal disease at age 52 years. Exome sequencing of the proband revealed an extremely rare missense heterozygous variant c.1711_1712CG>TC; p.(Arg571Ser) in LMNA which was confirmed by Sanger sequencing in both the patients. Interestingly, the mutation had no effect on mRNA splicing or relative expression of lamin A or C mRNA and protein in the lymphoblasts. Our observations suggest that mutant lamin C disrupts its interaction with other cellular proteins resulting in generalized lipodystrophy due to defective development and maintenance of adipose tissue.

Protease inhibitors (PIs) are regulatory proteins found in numerous animal tissues and fluids, plants, and microorganisms that reduce and inhibit the exacerbated and uncontrolled activity of the target proteases. Specific PIs are also effective tools for inactivating proteases involved in human diseases like arthritis, pancreatitis, hepatitis, cancer, AIDS, thrombosis, emphysema, hypertension, and muscular dystrophy among others. Plant PIs-small peptides with a high content of cystine residues in disulfide bridges-possess a remarkable resistance to heat treatment and a high stability against shifts in pH, denaturing agents, ionic strength, and proteolysis. In recent years, novel biologic activities have been reported for plant PIs, including antimicrobial, anticoagulant, antioxidant action plus inhibition of tumor-cell growth; thus pointing to possible applications in medicine, agriculture, and biotechnology. In this review, we provide a comparative overview of plant-PIs classifying them in four groups according of their thermal and pH stability (high stability and hyperstable -to temperature and to pHs-, respectively), then emphasizing the relevance of the physicochemical characteristics of these proteins for potential biotechnological and industrial applications. Finally, we analyze the biologic activities of the stable protease inhibitors previously characterized that are the most relevant to potential applications in biomedicine, the food industry, and agriculture.
