In the present work, sheets of Papyrus ( L.), manufactured by lamination from strips pre-treated with different treatments, were evaluated for their technological and fungal infestation properties ( AFl375, Ani245 and Cgl311). The results showed that the highest values of tensile strength, tear strength, burst index and double-fold number were observed in papyrus sheets produced from strips treated with nano-cellulose (0.25%), dimethyl sulfoxide (DMSO 10%), Tylose (0.25%) and nano-cellulose (0.5%), with values of 98.90 N·m/g, 2343.67 mN·m²/g, 1162 kpa·m²/g and 8.33, respectively. The percentage of brightness ranged from 49.7% (strips treated with KOH 2% + 100 mL NaClO) to 9.6% (strips treated with bark extract 2%), while the percentage of darkness ranged from 99.86% (strips treated with leaf extract 2% or bark extract 0.5%) to 67.26% (strips treated with NaOH (2%) + 100 mL NaClO). From the SEM examination, sheets produced from treated strips with extracts from and or showed no growths of and . Additionally, other pre-treatments, such as Nano-cellulose+Tylose 0.5% (1:1 /) and Tylose 0.5%, were also found to have no growth of . In conclusion, strips pre-treated with nanomaterials and extracts were enhanced in terms of the technological and antifungal properties of produced Papyrus sheets, respectively.

Background: 65% of persons with dementia (PWD) suffer from disturbed sleeping patterns and 28% experience vision related falls. Improved lighting has been shown in numerous studies since the 1980s to mitigate these effects.
Method: Computer code was written to optimize the spectra and intensity of light for vision and non-vision purposes over a 24-hour cycle based on off-the-shelf LEDs.

Background: 6-Nitrodopamine (6-ND) released from rat vas deferens acts an endogenous modulator of vas deferens contractility.
Objectives: To investigate whether rat isolated seminal vesicles (RISV) releases 6-ND, the mechanisms involved in the release, and the modulatory role of 6-ND on tissue contractility.
Methods: Rat seminal vesicles were removed and placed in Krebs-Henseleit's solution at 37°C for 30 min, and an aliquot was used to analyze the concentrations of 6-ND, dopamine, noradrenaline, and adrenaline by liquid chromatography with tandem mass spectrometry (LC-MS/MS).
It is well known that keratinized mucosa (KM) plays a crucial role for maintaining peri implant health and esthetic outcomes. The Strip Gingival Graft (SGG) technique, which involved an apically positioned flap (APF), in combination with an autogenous SGG and a xenogeneic collagen matrix (XCM), demonstrated its efficacy in re-establishing an adequate amount of KM width at implant sites. Nevertheless, it is still unclear whether harvesting the SGG from the palate (pSGG) or from the buccal aspect of natural dentition (bSGG) affects the esthetic outcomes at the augmented implant sites.

Editor's note: This is the next installment in a series on electrocardiogram (ECG) interpretation. Nurses in all settings should know the basics, as medications and physiological changes can cause cardiac arrhythmias. Each article will start with a brief case scenario and an ECG strip and then take you step by step through analyzing the heart rhythm.
