Neuroprotective mechanisms of red clover and soy isoflavones in Parkinson's disease models.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by nigrostriatal degeneration and the spreading of aggregated forms of the presynaptic protein α-synuclein (aSyn) throughout the brain. PD patients are currently only treated with symptomatic therapies, and strategies to slow or stop the progressive neurodegeneration underlying the disease's motor and cognitive symptoms are greatly needed. The time between the first neurobiochemical alterations and the initial presentation of symptoms is thought to span several years, and early neuroprotective dietary interventions could delay the disease onset or slow PD progression.

[Posttraumatic Osteomyelitis: Improvement in Outcome by Negative Pressure Wound Therapy with Instillation Technique].

Posttraumatic Osteomyelitis: Improvement in Outcome by Negative Pressure Wound Therapy with Instillation Technique Abstract. Surgical treatment of post-traumatic (fistula) osteomyelitis can be difficult and is associated with an increased risk of later recurrence. Very often osteomyelitis is accompanied by a soft tissue (defective) wound.

Lumbee traditional medicine: Neuroprotective activities of medicinal plants used to treat Parkinson's disease-related symptoms.

Ethnopharmacological Relevance: Parkinson's disease (PD) is a neurodegenerative disorder characterized by a loss of dopaminergic neurons in the substantia nigra pars compacta and the presence in surviving neurons of Lewy body inclusions enriched with aggregated forms of the presynaptic protein α-synuclein (aSyn). Although current therapies provide temporary symptomatic relief, they do not slow the underlying neurodegeneration in the midbrain. In this study, we analyzed contemporary herbal medicinal practices used by members of the Lumbee tribe to treat PD-related symptoms, in an effort to identify safe and effective herbal medicines to treat PD.

In vitro lipolytic, antioxidant and anti-inflammatory activities of roasted pistachio kernel and skin constituents.

A comprehensive phytochemical analysis was conducted on pistachios to identify the differential contributions of skin and kernel phytochemicals to in vitro bioactivity. Qualitative and quantitative analyses of skin and kernel non-polar extracts (SNP and KNP, respectively) indicated that the major components are fatty acids (696.36 and 879.

Chemical composition, antioxidant and anti-inflammatory properties of pistachio hull extracts.

Phytochemical and bioactivity analyses of pistachio hulls revealed the presence of anacardic acids (3198mg/100g), fatty acids (1500mg/100g), and phytosterols (192mg/100g) as major components. Carotenoids (4.93mg/100g), chlorophylls (10.

Characterization of Phenolic Compounds and Antioxidant and Anti-inflammatory Activities from Mamuyo (Styrax ramirezii Greenm.) Fruit.

Extracts of Styrax ramirezii Greenm., a fruit traditionally valued for health and wellness in Mexico, were analyzed phytochemically and evaluated for antioxidant and anti-inflammatory activity. Six norneolignans were identified by HPLC-TOF-MS, and the two major compounds were isolated for further evaluation.

Phenylphenalenones and oxabenzochrysenones from the Australian plant Haemodorum simulans.

Chemical investigation of the Australian plant Haemodorum simulans (Haemodoraceae) resulted in the isolation of two new phenylphenalenones, haemoxiphidone and haemodordioxolane from the bulbs together with the first report of an oxabenzochrysenone glycoside, haemodoroxychrysenose from the aerial parts of the plant. Also isolated were two previously described phenylphenalenones 5,6-dimethoxy-7-phenyl-1H,3H-naphtho[1,8-cd]pyran-1,3-dione and haemodorone and two oxabenzochrysenones 5-hydroxyl-2-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one and 5-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one. The X-ray structure of the phenylphenalenone 5,6-dimethoxy-7-phenyl-1H,3H-naphtho[1,8-cd]pyran-1,3-dione was secured for the first time.

Application of HPLC-NMR in the identification of plocamenone and isoplocamenone from the marine red alga Plocamium angustum.

A combination of on-line HPLC-NMR and off-line chemical investigations has resulted in the identification of the previously reported polyhalogenated monoterpene plocamenone, together with the new structural analogue isoplocamenone from the crude extract of the marine alga Plocamium angustum. On-flow and stop-flow HPLC-NMR analyses (including the acquisition of WET 2D NMR spectra) rapidly assisted in the identification of the major component plocamenone and in the partial identification of its unstable double bond isomer isoplocamenone. Conventional off-line isolation and structural characterization techniques were employed to unequivocally confirm both structures, leading to a structural revision for plocamenone, as well as to obtain sufficient quantities for biological testing.

On-line (HPLC-NMR) and off-line phytochemical profiling of the Australian plant, Lasiopetalum macrophyllum.

On-line (HPLC-NMR) and off-line (HPLC, NMR and MS) methodologies were used to profile the constituents present in the crude extract of Lasiopetalum macrophyllum. On-flow and stop-flow HPLC-NMR supported the presence of trans-tiliroside and permitted partial identification of cis-tiliroside and 4'-methoxy-trans-tiliroside. Off-line isolation led to the unequivocal identification of four flavanoid glycosides including a new structural derivative, 4'-methoxycis-tiliroside.

Negative pressure wound treatment with polyvinyl alcohol foam and polyhexanide antiseptic solution instillation in posttraumatic osteomyelitis.

In a retrospective, case-control cohort study an assessment was made of the clinical outcome of patients with osteomyelitis treated with a new modality of negative pressure wound therapy, so called negative pressure instillation therapy. In this approach, after surgical debridement, a site of osteomyelitis is treated with negative pressure of at least 300 mmHg applied through polyvinyl alcohol dressing. The polyvinyl alcohol foam is irrigated through the tubes three times a day with a polyhexanide antiseptic solution.
