Elkady, Omar A; Mannaa, Islam M; El Bishbishy, Mahitab H
Spirulina platensis, a blue-green algae belonging to family Phormidiaceae, is well-known for its unique nutritional profle
and high protein content. This study aims to isolate its proteins, formulate them into a cream and evaluate its potential
as a hair treatment. S. platensis were collected from Nuweiba, Egypt and its protein was extracted, analyzed and used to
prepare a cream. The cream was applied on natural hair strands compared to a control cream containing no protein. Both
hair strands groups were observed via Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM),
Atomic Force Microscopy (AFM) and evaluated by Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy,
as well as, thermal analysis tests including thermogravimetric analysis (TGA) and Diferential Scanning Calorimetry (DSC).
The SEM images of the test group showed more intact cuticle with the absence of cracks and holes, also, the TEM images
showed stronger non-porous cuticle compared to the control group. The AFM images of the test group was smoother
with lower roughness average and step height compared to the control group. On the other hand, the raman spectra
showed diferent band intensities for disulfde bonds and C-S bonds as well as increased number of b sheet conformations in the test group which is responsible for the smoothing efect. The thermal analysis tests revealed a clear diference between both groups as an indication of improved keratin structure on the test group. S. platensis proteins could
be introduced as a potential candidate for hair care products.

Prevalence of Forward Head Posture among Cleaning Workers and Its Correlation to Physical Workload
Ibrahim, Heba Mohamed; Abdel Raoof, Neveen Abdel Latif; Diab, Olfat Abdelrahman; Khalil, Aya Abdelhamid
Background: Cleaning workers often perform repeated activities in awkward postures, exposing them to postural
malalignment and musculoskeletal disorders.
Objective: This study aimed to investigate the prevalence of forward head posture (FHP) among cleaning workers
and to determine its associated risk factors with a correlational analysis to physical workload.
Methods: This cross-sectional observational research was conducted using Photogrammetry to determine the
craniovertebral angle and a Rapid Upper Limb Assessment (RULA) working sheet to evaluate the physical workload
and the risk level for developing musculoskeletal disorders (MSDs) in 104 cleaning workers.
Results: The prevalence of forward head posture among cleaning workers was 61.54% with 95% CI (51.94- 70.32%).
FHP was significantly associated with higher weight status and working years (p<0.05). A Binary logistic regression
determined that overweight and obese participants were 0.11 times more likely to have FHP compared to normal
weight participants (Odds Ratio = 0.11, 95% CI 0.04-0.34). Participants with working 5-30 years were 0.23 times
more likely to have FHP than participants with 1- 4 working years (Odds Ratio = 0.23, 95% CI 20.09-0.53). RULA
score among them was 6.33 ± 0.73. There is a significant moderate positive correlation between the FHP and RULA
score (rpb = 0.49 p < 0.05).
Conclusion: 61.54% of cleaning workers exhibited forward head posture. High BMI and long working years were the
associated risk factors. High RULA scores emphasized the need for preventive actions to lower the risk of developing
FHP and other MSDs.

EFFECT OF USING ATHLETIC RIGID TAPE FOR FOOT REALIGNMENT ON BALANCE IN SELECTED SPORT’S ACTIVITIES
Othman, Yasmin M; Diab, Olfat A; Abdel Raoof, Neveen A
Background: In the world of sports, balance is essential in enhancing performance and reducing the risk
of injuries. Basketball, being a dynamic as well as physically demanding sport, demands athletes to exhibit
exceptional balance and stability. Various techniques and interventions have been explored to optimize balance
and prevent injuries among basketball players. One such intervention is the use of anti-pronation taping, which
aims to realign the foot and ankle
Purpose: The objective of this study was to examine the impact of using athletic rigid tape for foot realignment
on balance in selected sport’s activities in pronated feet.
Materials and Methods: Forty-Two female basketball players aged from fifteen to thirty years were included in
this study. The participants were allocated into two groups using a random assignment method; Rigid athletic
tape was applied to one group and no taping was applied to the other group. Dynamic Postural Balance was
assessed using Biodex Balance System before and after 2 weeks from participation for the two groups. Results:
There was improvement in both groups (Study and control groups) with significant improvement in study group
(at P value < 0.05).
Conclusion: Using athletic rigid taping for realignment can improve balance in pronated foot in basketball
players. This may redirect the attention of sport’s rehabilitation specialists to include rigid taping to improve the
performance of in sports including jumping as well as for prevention of injury.

Effect of Trunk Muscles Strengthening on Hip Abductors Strength and Endurance in Young Adults
Abdel latif, Ahmed S; Abdel Raoof, Neveen A; Diab, Olfat A
Background: Hip abductors muscles are extremely important during several activities and its weakness can affect our daily
life activities. Objective: This study aimed to investigate the effect of strengthening trunk muscles on Hip abductors
strength and endurance in young adults.
Patients and methods: This study was conducted on 58 patients. They were assigned into 2 equal groups: Group A
(Control group) consisted of 29 subjects received conventional hip abduction exercises from standing position against a
theraband and group B (Study group) consisted of 29 subjects received the same hip abduction exercises plus a curl up
exercise performed 3 days a week at October University for Modern Sciences and Art (MSA). Results: There was
statistically significant differences in the mean values of maximum abductor isometric strength post-study between both
groups (p= 0.038) in favor of group B, in the mean values of time of unilateral bridging test post-study between both groups
(p= 0.046) in favor of group B and in the mean values of time of hip abductor endurance post-study between both groups
(p= 0.005) in favor to group B.
Conclusion: Curl up exercise combined with hip abduction resisted exercise against an elastic band did a significant
improvement regarding the maximum hip abductors isometric strength, and there was a significant difference in Hip
abductors endurance compared to doing just hip abductors resisted exercise only. It’s recommended to add curl up exercise
in programs aimed to improve Hip abductors strength and endurance.
